Node javascript array deconstruction with custom applied function

Admin 1

I have an array containing two strings: '1' and '5' for example. I want to save those two strings into parameters, but already as integer numbers. Currently, the code looks like this:

const data = ['1', '5'];
const [min_str, max_str] = data;
const min = parseInt(min_str, 10);
const max = parseInt(max_str, 10);

console.log(typeof min_str, typeof max_str, typeof min, typeof max)

Is there a way to reduce this code to one line, such that parseInt has already been applied to min_str and max_str?

You could map the data before destructing

const [min, max] = data.map(d => parseInt(d, 10));

Maybe you can use map()

const [min_str, max_str] = data.map(x => parseInt(x, 10));

If the strings are only numbers inside strings. You can also use Number

const [min_str, max_str] = data.map(Number);

You could get min and max values with Math methods.

This approach does not rely on the order of the array nor expect only two values.

const
    data = ['1', '5'],
    [min, max] = ['min', 'max'].map(k => Math[k](...data));

console.log(min, max);

You can map the data using Number

const [min, max] = ["1", "5"].map(Number);
console.log(min, max);

const [min_str, max_str] = data.map(a => parseInt(a, 10));
