4 months old and I concur concur. I also used sort not realizing how inefficient it is. Thanks for the learning.

Your comment is 2 years old but I concur.

I'm just starting, and my solution was just like this one above.
But excellent point! Seeing your thought make me think a lot different about somethings.
Three years old comment, but really helpful!

Amen!

Nice code!

this made me laugh

Always amazing when I complete a Kata and see a much simpler version. Reminder of how little I know.

This is insane, I love this approach. I was trying to wrap my brain around it for a while. Let me make sure I understand this correctly. When the functions execution context is reached, it then gets executed due to the IIFE ( Immediately Invoked Function Expression ) passing in the Number object's prototype allowing for these functions to be available for any number object? - Brilliant

Using filter or forEach, while more succinct, is less efficient for this sort of thing, since these functions will continue until the entire array has been iterated, whereas a normal loop (or functions like every/some) can be broken as soon as an element is found that does not meet the criteria.

Didn't know about filter! Thanks!

Nevermind. I see the kata has an error within the tests regarding, JS and CoffeeScript.

Works fine when submitting.

I think I will set this one aside for now. I am at work (none coding job) and I want to be able to take my time with this one.

I think this is awesome! You practically built an entire utility for this one line of code solution! I give you a +1 for this!
