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         


        

Answer 1

Here is the piece of code that achieves OP's goal using a single function :

const sources = images.flatMap( (img) =>
    (img.split('.').pop() === "json") ?  [] : [img]
)

See the developer mozilla documentation of flatMap here
