I'll leave it to the original authors to decide the validity of this change but this PR should be restricted to the described change.
E.g., the change to use forEach doesn't actually improve the code. And the style change of adding brackets around an if is also not meaningful.

Why this change? This isn't faster or better.

No is not, but if you are invoking a chain-able method for an array, might as well chain and iterate no?

I would assume there's a reason the original test case used both setImmediate and setTimeout.
…Timeout & refactor do not need to redifine duration

The following
