iterate-function

Repeatedly apply a function.

  iterate(limit, inital_value, func)

    // or:

  iterate(limit, func)

func gets passed two arguments:

  iterate(limit, inital_value, func(index, applied_value) { do_stuff(); })

'index' is the current index of the loop. 'applied_value' is the return value of that function for the previous iteration.

Simple example:

    iterate(3, function(i) { console.log(i) })
    > 0
    > 1
    > 2

Using the applied value to get the powers of 2:

  power = iterate(4, 1, function(i, applied) { return applied * 2 });
  > 16
