I am trying to loop through an array. I have the following code:

 var currnt_image_list= '21,32,234,223';
 var substr = currnt_image_list.split(','); // array here

Am trying to get all the data out of the array. Can some one lead me in the right path please?

ES6 syntax with arrow function and interpolation:

var data=["a","b","c"];
$(data).each((index, element) => {
        console.log(`current index : ${index} element : ${element}`)
    });

Try this:

$.grep(array, function(element) {

})

$.map(data,function(elem) {...})

$.map(data,function(elem){
   console.log(elem);
})

Alternative ways of iteration through array/string with side effects

var str = '21,32,234,223';
var substr = str.split(',');

substr.reduce((a,x)=> console.log('reduce',x), 0)        // return undefined

substr.every(x=> { console.log('every',x); return true}) // return true

substr.some(x=> { console.log('some',x); return false})  // return false

substr.map(x=> console.log('map',x));                    // return array
 
str.replace(/(\d+)/g, x=> console.log('replace',x))      // return string

  for(var key in substr)
{
     // do something with substr[key];
