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

You could also try a recursive function, though @xdazz's looks rather attractive.

var indexOfId = function(arr, id, index) {
    if (!index) { index = 0; }
    if (arr[index].id == id) {
      return index;
    }
    return ((index += 1) >= arr.length) ? -1 : indexOfId(arr, id, index);
};
