Getting index of an array's element based on its properties

Question

I have a JavaScript array of objects like this:

var myArray = [{...}, {...}, {...}];

Each object has unique id among other pro

Answer 1

Why not simply make a loop ?

function indexOfId(array, id) {
    for (var i=0; i

The fact that there are many facilities in js (or js libraries) doesn't mean you must not, sometimes, write a loop. That's fast and simple.
