Array Prototype ForEach: coding question

Available question text

Implement a polyfill for Array.prototype.forEach that iterates an array in order and invokes a provided callback for each present element with arguments (element, index, array) using an optional thisArg. It should mimic native behavior: no return value, skip holes in sparse arrays, and throw if the callback is not a function.
