It's easy enough to write your own comparison function:

function compare( a, b ) {
  if ( a.last_nom < b.last_nom ){
    return -1;
  }
  if ( a.last_nom > b.last_nom ){
    return 1;
  }
  return 0;
}

objs.sort( compare );

Or inline (c/o Marco Demaio):

objs.sort((a,b) => (a.last_nom > b.last_nom) ? 1 : ((b.last_nom > a.last_nom) ? -1 : 0))

Or simplified for numeric (c/o Andre Figueiredo):

objs.sort((a,b) => a.last_nom - b.last_nom); // b - a for reverse sort

You can also create a dynamic sort function that sorts objects by their value that you pass:

function dynamicSort(property) {
    var sortOrder = 1;
    if(property[0] === "-") {
        sortOrder = -1;
        property = property.substr(1);
    }
    return function (a,b) {
        /* next line works with strings and numbers, 
         * and you may want to customize it to your needs
         */
        var result = (a[property] < b[property]) ? -1 : (a[property] > b[property]) ? 1 : 0;
        return result * sortOrder;
    }
}

So you can have an array of objects like this:

var People = [
    {Name: "Name", Surname: "Surname"},
    {Name:"AAA", Surname:"ZZZ"},
    {Name: "Name", Surname: "AAA"}
];

...and it will work when you do:

People.sort(dynamicSort("Name"));
People.sort(dynamicSort("Surname"));
People.sort(dynamicSort("-Surname"));

Actually this already answers the question. Below part is written because many people contacted me, complaining that it doesn't work with multiple parameters.

Multiple Parameters

You can use the function below to generate sort functions with multiple sort parameters.

function dynamicSortMultiple() {
    /*
     * save the arguments object as it will be overwritten
     * note that arguments object is an array-like object
     * consisting of the names of the properties to sort by
     */
    var props = arguments;
    return function (obj1, obj2) {
        var i = 0, result = 0, numberOfProperties = props.length;
        /* try getting a different result from 0 (equal)
         * as long as we have extra properties to compare
         */
        while(result === 0 && i < numberOfProperties) {
            result = dynamicSort(props[i])(obj1, obj2);
            i++;
        }
        return result;
    }
}

Which would enable you to do something like this:

People.sort(dynamicSortMultiple("Name", "-Surname"));

Subclassing Array

For the lucky among us who can use ES6, which allows extending the native objects:

class MyArray extends Array {
    sortBy(...args) {
        return this.sort(dynamicSortMultiple(...args));
    }
}

That would enable this:

MyArray.from(People).sortBy("Name", "-Surname");

Case sensitive

arr.sort((a, b) => a.name > b.name ? 1 : -1);

Case Insensitive

arr.sort((a, b) => a.name.toLowerCase() > b.name.toLowerCase() ? 1 : -1);

Useful Note

If no change in order (in case of the same strings) then the condition > will fail and -1 will be returned. But if strings are same then returning 1 or -1 will result in correct output

The other option could be to use >= operator instead of >

var objs = [ 
    { first_nom: 'Lazslo', last_nom: 'Jamf'     },
    { first_nom: 'Pig',    last_nom: 'Bodine'   },
    { first_nom: 'Pirate', last_nom: 'Prentice' }
];


// Define a couple of sorting callback functions, one with hardcoded sort key and the other with an argument sort key
const sorter1 = (a, b) => a.last_nom.toLowerCase() > b.last_nom.toLowerCase() ? 1 : -1;
const sorter2 = (sortBy) => (a, b) => a[sortBy].toLowerCase() > b[sortBy].toLowerCase() ? 1 : -1;

objs.sort(sorter1);
console.log("Using sorter1 - Hardcoded sort property last_name", objs);

objs.sort(sorter2('first_nom'));
console.log("Using sorter2 - passed param sortBy='first_nom'", objs);

objs.sort(sorter2('last_nom'));
console.log("Using sorter2 - passed param sortBy='last_nom'", objs);

If you have duplicate last names you might sort those by first name-

obj.sort(function(a,b){
  if(a.last_nom< b.last_nom) return -1;
  if(a.last_nom >b.last_nom) return 1;
  if(a.first_nom< b.first_nom) return -1;
  if(a.first_nom >b.first_nom) return 1;
  return 0;
});

As of 2018 there is a much shorter and elegant solution. Just use. Array.prototype.sort().

Example:

var items = [
  { name: 'Edward', value: 21 },
  { name: 'Sharpe', value: 37 },
  { name: 'And', value: 45 },
  { name: 'The', value: -12 },
  { name: 'Magnetic', value: 13 },
  { name: 'Zeros', value: 37 }
];

// sort by value
items.sort(function (a, b) {
  return a.value - b.value;
});

Old answer that is not correct:

arr.sort((a, b) => a.name > b.name)

UPDATE

From Beauchamp's comment:

arr.sort((a, b) => a.name < b.name ? -1 : (a.name > b.name ? 1 : 0))

More readable format:

arr.sort((a, b) => {
  if (a.name < b.name) return -1
  return a.name > b.name ? 1 : 0
})

Without nested ternaries:

arr.sort((a, b) => a.name < b.name ? - 1 : Number(a.name > b.name))

Explanation: Number() will cast true to 1 and false to 0.

You can use Easiest Way: Lodash

(https://lodash.com/docs/4.17.10#orderBy)

This method is like _.sortBy except that it allows specifying the sort orders of the iteratees to sort by. If orders is unspecified, all values are sorted in ascending order. Otherwise, specify an order of "desc" for descending or "asc" for ascending sort order of corresponding values.

Arguments

collection (Array|Object): The collection to iterate over. [iteratees=[_.identity]] (Array[]|Function[]|Object[]|string[]): The iteratees to sort by. [orders] (string[]): The sort orders of iteratees.

Returns

(Array): Returns the new sorted array.

var _ = require('lodash');
var homes = [
    {"h_id":"3",
     "city":"Dallas",
     "state":"TX",
     "zip":"75201",
     "price":"162500"},
    {"h_id":"4",
     "city":"Bevery Hills",
     "state":"CA",
     "zip":"90210",
     "price":"319250"},
    {"h_id":"6",
     "city":"Dallas",
     "state":"TX",
     "zip":"75000",
     "price":"556699"},
    {"h_id":"5",
     "city":"New York",
     "state":"NY",
     "zip":"00010",
     "price":"962500"}
    ];
    
_.orderBy(homes, ['city', 'state', 'zip'], ['asc', 'desc', 'asc']);

I haven't seen this particular approach suggested, so here's a terse comparison method I like to use that works for both string and number types:

const objs = [ 
  { first_nom: 'Lazslo', last_nom: 'Jamf'     },
  { first_nom: 'Pig',    last_nom: 'Bodine'   },
  { first_nom: 'Pirate', last_nom: 'Prentice' }
];

const sortBy = fn => {
  const cmp = (a, b) => -(a < b) || +(a > b);
  return (a, b) => cmp(fn(a), fn(b));
};

const getLastName = o => o.last_nom;
const sortByLastName = sortBy(getLastName);

objs.sort(sortByLastName);
console.log(objs.map(getLastName));

Explanation of sortBy()

sortBy() accepts a fn that selects a value from an object to use in comparison, and returns a function that can be passed to Array.prototype.sort(). In this example, we're comparing o.last_nom. Whenever we receive two objects such as

a = { first_nom: 'Lazslo', last_nom: 'Jamf' }
b = { first_nom: 'Pig', last_nom: 'Bodine' }

we compare them with (a, b) => cmp(fn(a), fn(b)). Given that

fn = o => o.last_nom

we can expand the comparison function to (a, b) => cmp(a.last_nom, b.last_nom). Because of the way logical OR (||) works in JavaScript, cmp(a.last_nom, b.last_nom) is equivalent to

if (a.last_nom < b.last_nom) return -1;
if (a.last_nom > b.last_nom) return 1;
return 0;

Incidentally, this is called the three-way comparison "spaceship" (<=>) operator in other languages.

Finally, here's the ES5-compatible syntax without using arrow functions:

var objs = [ 
  { first_nom: 'Lazslo', last_nom: 'Jamf'     },
  { first_nom: 'Pig',    last_nom: 'Bodine'   },
  { first_nom: 'Pirate', last_nom: 'Prentice' }
];

function sortBy(fn) {
  function cmp(a, b) { return -(a < b) || +(a > b); }
  return function (a, b) { return cmp(fn(a), fn(b)); };
}

function getLastName(o) { return o.last_nom; }
var sortByLastName = sortBy(getLastName);

objs.sort(sortByLastName);
console.log(objs.map(getLastName));

Instead of using a custom comparison function, you could also create an object type with custom toString() method (which is invoked by the default comparison function):

function Person(firstName, lastName) {
    this.firtName = firstName;
    this.lastName = lastName;
}

Person.prototype.toString = function() {
    return this.lastName + ', ' + this.firstName;
}

var persons = [ new Person('Lazslo', 'Jamf'), ...]
persons.sort();

Try this,

UPTO ES5

//Ascending Sort
items.sort(function (a, b) {
   return a.value - b.value;
});


//Descending Sort
items.sort(function (a, b) {
   return b.value - a.value;
});


IN ES6 & above:

// Ascending sort
items.sort((a, b) => a.value - b.value);

// Descending Sort
 items.sort((a, b) => b.value - a.value);

Use JavaScript sort method

The sort method can be modified to sort anything like an array of numbers, strings and even objects using a compare function.

A compare function is passed as an optional argument to the sort method.

This compare function accepts 2 arguments generally called a and b. Based on these 2 arguments you can modify the sort method to work as you want.

1. If the compare function returns less than 0, then the sort() method sorts a at a lower index than b. Simply a will come before b.
2. If the compare function returns equal to 0, then the sort() method leaves the element positions as they are.
3. If the compare function returns greater than 0, then the sort() method sorts a at greater index than b. Simply a will come after b.

Use the above concept to apply on your object where a will be your object property.

var objs = [
  { first_nom: 'Lazslo', last_nom: 'Jamf' },
  { first_nom: 'Pig', last_nom: 'Bodine' },
  { first_nom: 'Pirate', last_nom: 'Prentice' }
];
function compare(a, b) {
  if (a.last_nom > b.last_nom) return 1;
  if (a.last_nom < b.last_nom) return -1;
  return 0;
}
objs.sort(compare);
console.log(objs)
// for better look use console.table(objs)

Why don't you write short code?

objs.sort((a, b) => a.last_nom > b.last_nom ? 1 : -1)

A simple function that sort an array of object by a property

function sortArray(array, property, direction) {
    direction = direction || 1;
    array.sort(function compare(a, b) {
        let comparison = 0;
        if (a[property] > b[property]) {
            comparison = 1 * direction;
        } else if (a[property] < b[property]) {
            comparison = -1 * direction;
        }
        return comparison;
    });
    return array; // Chainable
}

Usage:

var objs = [ 
    { first_nom: 'Lazslo', last_nom: 'Jamf'     },
    { first_nom: 'Pig',    last_nom: 'Bodine'   },
    { first_nom: 'Pirate', last_nom: 'Prentice' }
];

sortArray(objs, "last_nom"); // Asc
sortArray(objs, "last_nom", -1); // Desc

This is my take on this:

The order parameter is optional and defaults to "ASC" for ascending order.

Works on accented chars and it's case insensitive.

NOTE: It sorts and returns the ORIGINAL array.

function sanitizeToSort(str) {
  return str
    .normalize('NFD')                   // REMOVE ACCENTED AND DIACRITICS
    .replace(/[\u0300-\u036f]/g,'')     // REMOVE ACCENTED AND DIACRITICS
    .toLowerCase()                      // SORT WILL BE CASE INSENSITIVE
  ;
}

function sortByProperty(arr, property, order="ASC") {
  arr.forEach((item) => item.tempProp = sanitizeToSort(item[property]));
  arr.sort((a,b) => order === "ASC" ?
      a.tempProp > b.tempProp ?  1 : a.tempProp < b.tempProp ? -1 : 0
    : a.tempProp > b.tempProp ? -1 : a.tempProp < b.tempProp ?  1 : 0
  );
  arr.forEach((item) => delete item.tempProp);
  return arr;
}

SNIPPET

function sanitizeToSort(str) {
  return str
    .normalize('NFD')                   // REMOVE ACCENTED CHARS
    .replace(/[\u0300-\u036f]/g,'')     // REMOVE DIACRITICS
    .toLowerCase()
  ;
}

function sortByProperty(arr, property, order="ASC") {
  arr.forEach((item) => item.tempProp = sanitizeToSort(item[property]));
  arr.sort((a,b) => order === "ASC" ?
      a.tempProp > b.tempProp ?  1 : a.tempProp < b.tempProp ? -1 : 0
    : a.tempProp > b.tempProp ? -1 : a.tempProp < b.tempProp ?  1 : 0
  );
  arr.forEach((item) => delete item.tempProp);
  return arr;
}

const rockStars = [
  { name: "Axl",
    lastname: "Rose" },
  { name: "Elthon",
    lastname: "John" },
  { name: "Paul",
    lastname: "McCartney" },
  { name: "Lou",
    lastname: "Reed" },
  { name: "freddie",             // WORKS ON LOWER/UPPER CASE
    lastname: "mercury" },
  { name: "Ámy",                 // WORKS ON ACCENTED CHARS TOO
    lastname: "winehouse"}
  
];

sortByProperty(rockStars,"name");

console.log("Ordered by name A-Z:");
rockStars.forEach((item) => console.log(item.name + " " + item.lastname));

sortByProperty(rockStars,"lastname","DESC");

console.log("\nOrdered by lastname Z-A:");
rockStars.forEach((item) => console.log(item.lastname + ", " + item.name));

You can use a reusable sort function.

Array.prototype.order = function (prop, methods = {}) {
    if (prop?.constructor == Object) {
        methods = prop;
        prop = null;
    }
    const [orderType_a, orderType_b] = methods.reverse ? [1, -1] : [-1, 1];

    const $ = x => prop
        ? methods.insensitive
            ? String(x[prop]).toLowerCase()
            : x[prop]
        : methods.insensitive
            ? String(x).toLowerCase()
            : x;

    const fn = (a, b) => $(a) < $(b) ? orderType_a : $(b) < $(a) ? orderType_b : 0;
    return this.sort(fn);
};

Its can be use to sort both Array and Object in array
.

let items = [{ x: "Z" }, 3, "1", "0", 2, { x: "a" }, { x: 0 }];
items
    .order("x", { insensitive: 1 })
    // [ { x: 0 }, { x: 'a' }, 3, '1', '0', 2, { x: 'Z' } ]
    .order({ reverse: 1 })
    // [ { x: 0 }, { x: 'a' }, 3, 2, { x: 'Z' }, '1', '0' ]
    .sort(x => typeof x == "string" || typeof x == "number" ? -1 : 0)
    // [ '0', '1', 2, 3, { x: 0 }, { x: 'a' }, { x: 'Z' } ]

1nd (optional) > to sort object contain in array.
2rd is method > { reverse: any, insensitive: any }

Way 1 :

You can use Underscore.js. Import underscore first.

 import * as _ from 'underscore';
 let SortedObjs = _.sortBy(objs, 'last_nom');

Way 2 : Use compare function.

function compare(first, second) {
     if (first.last_nom < second.last_nom)
         return -1;
     if (first.last_nom > second.last_nom)
       return 1;
    return 0;
 }

objs.sort(compare);

Simple answer:

objs.sort((a,b)=>a.last_nom.localeCompare(b.last_nom))

Details:

Today it is very simple, You can compare strings with localeCompare. As the Mozilla Doc says:

The localeCompare() method returns a number indicating whether a reference string comes before, or after, or is the same as the given string in sort order.

    //example1:
    console.log("aaa".localeCompare("aab")); //-1
    console.log("aaa".localeCompare("aaa")); //0
    console.log("aab".localeCompare("aaa")); //1

    //example2:
    const a = 'réservé'; // with accents, lowercase
    const b = 'RESERVE'; // no accents, uppercase

    console.log(a.localeCompare(b));
    // expected output: 1
    console.log(a.localeCompare(b, 'en', { sensitivity: 'base' }));
    // expected output: 0

For more details see Mozilla doclocaleCompare:

It works for me. Here It will keep undefined to the end.

 function sort(items, property, direction) {

    function compare(a, b) {
      if(!a[property] && !b[property]) {
        return 0;
      } else if(a[property] && !b[property]) {
        return -1;
      } else if(!a[property] && b[property]) {
        return 1;
      } else {
        const value1 = a[property].toString().toUpperCase(); // ignore upper and lowercase
        const value2 = b[property].toString().toUpperCase(); // ignore upper and lowercase
        if (value1 < value2) {
          return direction === 0 ? -1 : 1;
        } else if (value1 > value2) {
          return direction === 0 ? 1 : -1;
        } else {
          return 0;
        }
        
      }
    }
    
    return items.sort(compare);
   } 
   
   var items = [
  { name: 'Edward', value: 21 },
  { name: 'Sharpe', value: 37 },
  { name: 'And', value: 45 },
  { name: 'The', value: -12 },
  { name: undefined, value: -12 },
  { name: 'Magnetic', value: 13 },
  { name: 'Zeros', value: 37 }
];
   console.log('Ascending Order:- ');
   console.log(sort(items, 'name', 0));
   console.log('Decending Order:- ');
   console.log(sort(items, 'name', 1));
    
    

Sorting objects with Intl.Collator for the specific case when you want natural sorting (i.e. 1,2,10,11,111).

const files = [
 {name: "1.mp3", size: 123},
 {name: "10.mp3", size: 456},
 {name: "100.mp3", size: 789},
 {name: "11.mp3", size: 123},
 {name: "111.mp3", size: 456},
 {name: "2.mp3", size: 789},
];

const naturalCollator = new Intl.Collator(undefined, {numeric: true, sensitivity: 'base'});

files.sort((a, b) => naturalCollator.compare(a.name, b.name));

console.log(files);

Browser support for Intl.Collator

I've been using this utility in a variety of projects and it works great. It's very modular too:

• Pass the name of the key to sort by
• Choose if the sorting is ascending or descending

sortArrayOfObjsByKeyUtil.js

// Sort array of objects by key
// ------------------------------------------------------------
const sortArrayOfObjsByKey = (array, key, ascdesc) =>
  array.sort((a, b) => {
    const x = a[key];
    const y = b[key];
    if (ascdesc === 'asc') {
      return x < y ? -1 : x > y ? 1 : 0;
    }
    if (ascdesc === 'desc') {
      return x > y ? -1 : x < y ? 1 : 0;
    }
    return null;
  });

It is also possible to make a dynamic sorting function when programming in TypeScript, but the types become more tricky in this case.

function sortByKey<O>(key: keyof O, decending: boolean = false): (a: O, b: O) => number {
    const order = decending ? -1 : 1;
    return (a, b): number => {
        const valA = a[key];
        const valB = b[key];
        if (valA < valB) {
            return -order;
        } else if (valA > valB) {
            return order;
        } else {
            return 0;
        }
    }
}

This can be used in TypeScript as the following:

const test = [
    {
        id: 0,
    },
    {
        id: 2,

this sorting funciton can be use for all object sorting,

• object

• deepObject

• numeric array

you can also do assending or desending sort by passing 1,-1 as param

Object.defineProperty(Object.prototype, 'deepVal', {
    enumerable: false,
    writable: true,
    value: function (propertyChain) {
        var levels = propertyChain.split('.');
        parent = this;
        for (var i = 0; i < levels.length; i++) {
            if (!parent[levels[i]])
                return undefined;
            parent = parent[levels[i]];
        }
        return parent;
    }
});


function dynamicSortAll(property,sortOrders=1) {

/**default sorting will be ascending order if you need descending order
sording you have to pass -1 as param**/

    var sortOrder = sortOrders;
   
    return function (a,b) {

   var result =(property? ((a.deepVal(property) > b.deepVal(property)) ? 1 : (a.deepVal(property) < b.deepVal(property)) ? -1 : 0) :((a > b) ? 1 : (a < b) ? -1 : 0))
  
        return result * sortOrder;
  
   
    }
}

deepObj = [
    {
        a: { a: 1, b: 2, c: 3 },
        b: { a: 4, b: 5, c: 6 }
    },
    { 
        a: { a: 3, b: 2, c: 1 },
        b: { a: 6, b: 5, c: 4 }
}];

let deepobjResult=deepObj.sort(dynamicSortAll('a.a',1))
console.log('deepobjResult :'+ JSON.stringify(deepobjResult))
var obj = [ 
    { first_nom: 'Lazslo', last_nom: 'Jamf'     },
    { first_nom: 'Pig',    last_nom: 'Bodine'   },
    { first_nom: 'Pirate', last_nom: 'Prentice' }
];
let objResult=obj.sort(dynamicSortAll('last_nom',1))
console.log('objResult :'+ JSON.stringify(objResult))

var numericObj=[1,2,3,4,5,6]

let numResult=numericObj.sort(dynamicSortAll(null,-1))

Deep

Based on this excellent tutorial I would like to develop Vlad Bezden answer and explain why localeCompare is better than standard comarison method like strA > strB. Lets run this example

console.log( 'Österreich' > 'Zealand' );  // We expect false
console.log( 'a' > 'Z' );                 // We expect false

The reason is that in JS all strings are encoded using UTF-16 and

let str = '';

// order of characters in JS
for (let i = 65; i <= 220; i++) {
  str += String.fromCodePoint(i); // code to character
}

console.log(str);

Capital letters go first (have small codes) and then go small letters and then go character Ö (after z). This is reason why we get true in first snippet - becasue operator > compare characters codes.

As you can see compare characters in diffrent languages is non trivial task - but luckily, modern browsers support the internationalization standard ECMA-402. So in JS we have strA.localeCompare(strB) which do the job (-1 means strA is less than strB; 1 means opposite; 0 means equal)

console.log( 'Österreich'.localeCompare('Zealand') ); // We expect -1
console.log( 'a'.localeCompare('Z') );                // We expect -1

I would like to add that localeCompare supports two parameters: language and additional rules

var objs = [ 
    { first_nom: 'Lazslo', last_nom: 'Jamf'     },
    { first_nom: 'Pig',    last_nom: 'Bodine'   },
    { first_nom: 'Pirate', last_nom: 'Prentice' },
    { first_nom: 'Test',   last_nom: 'jamf'     } 
];

objs.sort((a,b)=> a.last_nom.localeCompare(b.last_nom,'en',{sensitivity:'case'}))

console.log(objs);

// in '>' comparison 'Jamf' will NOT be next to 'jamf'

Hers a function you can use to sort the list by multiple objects, where if the first object is equal, the second order will be used as a fallback. empty values should also be ignored to fallback order if possible.

function sortObjects(list, orderBy){
    list.sort(function(a, b){
        let byIndex = 0;
        let order = orderBy[byIndex];
        while(!a[order.by] || !b[order.by] || a[order.by] === b[order.by]){
            byIndex++;
            if(byIndex >= orderBy.length){break;}
            order = orderBy[byIndex];
        }
        if(!a[order.by] || !b[order.by] || a[order.by] === b[order.by]){
            return false;
        }
        if(order.desc){
            return a[order.by] < b[order.by];
        }
        return a[order.by] > b[order.by];
    });
    return list;
}

usage:

var objs = [
    {a: 10, b: 20, c: 30},
    {a: 30, b: 10, c: 20},
    {a: 20, b: 10, c: 30},
];

sortObjectList(objs, [{by: 'a'}]);
[
    {a: 10, b: 20, c: 30},
    {a: 20, b: 10, c: 30},
    {a: 30, b: 10, c: 20},
]

sortObjectList(objs, [{by: 'a', desc: true}]);
[
    {a: 30, b: 10, c: 20},
    {a: 20, b: 10, c: 30},
    {a: 10, b: 20, c: 30},
]

sortObjectList(objs, [{by: 'b', desc: true}, {by: 'c'}]);
[
    {a: 10, b: 20, c: 30},
    {a: 30, b: 10, c: 20},
    {a: 20, b: 10, c: 30},
]

another example:

var objs = [
    {a: 5, b: 5},
    {a: 10, b: 15},
    {a: 15, b: 25},
    {b: 10},
    {b: 20},
    {a: 10, b: 30},
    {a: 10, b: 12},
];

sortObjectList(objs, [{by: 'a'}, {by: 'b'}]);
[
    {a: 5, b: 5},
    {b: 10},
    {a: 10, b: 12},
    {a: 10, b: 15},
    {b: 20},
    {a: 10, b: 30},
    {a: 15, b: 25},
]

For fp-holics:

const objectSorter = (p)=>(a,b)=>((a,b)=>a>b?1:a<b?-1:0)(a[p], b[p]);
objs.sort(objectSorter('first_nom'));

In case you have nested objects

const objs = [{
        first_nom: 'Lazslo',
        last_nom: 'Jamf',
        moreDetails: {
            age: 20
        }
    }, {
        first_nom: 'Pig',
        last_nom: 'Bodine',
        moreDetails: {
            age: 21
        }
    }, {
        first_nom: 'Pirate',
        last_nom: 'Prentice',
        moreDetails: {
            age: 22
        }
    }];

nestedSort = (prop1, prop2 = null, direction = 'asc') => (e1, e2) => {
        const a = prop2 ? e1[prop1][prop2] : e1[prop1],
            b = prop2 ? e2[prop1][prop2] : e2[prop1],
            sortOrder = direction === "asc" ? 1 : -1
        return (a < b) ? -sortOrder : (a > b) ? sortOrder : 0;
    }

and call it like

objs.sort(nestedSort("last_nom"));
objs.sort(nestedSort("last_nom", null, "desc"));
objs.sort(nestedSort("moreDetails", "age"));
objs.sort(nestedSort("moreDetails", "age", "desc"));

//Try this way


let objs = [ 
        { first_nom: 'Lazslo', last_nom: 'Jamf'     },
        { first_nom: 'Pig',    last_nom: 'Bodine'   },
        { first_nom: 'Pirate', last_nom: 'Prentice' }
    ];
    const compareBylastNom = (a, b) => {
        // converting to uppercase to have case-insensitive comparison
        const name1 = a.last_nom.toUpperCase();
        const name2 = b.last_nom.toUpperCase();
    
        let comparison = 0;
    
        if (name1 > name2) {
            comparison = 1;
        } else if (name1 < name2) {
            comparison = -1;
        }
        return comparison;
    }
    console.log(objs.sort(compareBylastNom));

let propName = 'last_nom';

let sorted_obj = objs.sort((a,b) => {
    if(a[propName] > b[propName]) {
        return 1;
    }
    if (a[propName] < b[propName]) {
        return -1;
    }
    return 0;
}

//This works because the js built-in sort function allows us to define our
//own way of sorting, this funny looking function is simply telling `sort` how to
//determine what is larger. 
//We can use `if(a[propName] > b[propName])` because string comparison is already built into JS
//if you try console.log('a' > 'z' ? 'a' : 'z')
//the output will be 'z' as 'a' is not greater than 'z'

I know there is already plenty of answers, including those with localeCompare ones, but if you don't want to/can't use localeCompare for some reason, I would suggest you to use this solution instead of ternary operator solution:

objects.sort((a, b) => (a.name > b.name) - (a.name < b.name));

Someone could say that it's not obvious what this code is doing, but in my opinion ternary operator is worse. If one ternary operator is readable enough, two ternary operators one embedded into another — really hard to read and ugly. One-line code with just two comparison operators and one minus operator is very simple to read and thus to reason.
