How to skip over an element in .map()?

Question

How can I skip an array element in .map?

My code:

var sources = images.map(function (img) {
    if(img.src.split(\'.\').pop() === \"json

I think the most simple way to skip some elements from an array is by using the filter() method.

By using this method (ES5) and the ES6 syntax you can write your code in one line, and this will return what you want:

let images = [{src: 'img.png'}, {src: 'j1.json'}, {src: 'img.png'}, {src: 'j2.json'}];

let sources = images.filter(img => img.src.slice(-4) != 'json').map(img => img.src);

console.log(sources);
