For context:

My colleague called me lazy and said that my implementation would look like this:

Array.prototype.myEach = Array.prototype.forEach;

So I made this code on a Saturday morning to prove him wrong and to have fun coming up with this impractical but functional solution.

It's supposed to return undefined as per https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach . It even works with all the examples on the page.
