Array.prototype.forEach
You can't break forEach. So use "some" or "every".
Array.prototype.some
some is pretty much the same as forEach but it break when the callback returns true.
Array.prototype.every
every is almost identical to some except it's expecting false to break the loop.
  1. var ary = ["javascript", "Java", "CoffeeScript", "TypeScript"];
  2.  
  3. ary.some(function (value, index, _ary) {
  4.     console.log(index + ": " + value);
  5.     return value === "CoffeeScript";
  6. });
  7. // output: 
  8. // 0: JavaScript
  9. // 1: Java
  10. // 2: CoffeeScript
  11.  
  12. ary.every(function(value, index, _ary) {
  13.     console.log(index + ": " + value);
  14.     return value.indexOf("Script") > -1;
  15. });
  16. // output:
  17. // 0: JavaScript
  18. // 1: Java
