JavaScript uses the deprecated Test framework

the only no-itertools solution )

Easy task, terrible instructions.

Remember: this is Codewars. Here, readability goes out the window.

let's save our computing cycles :)

How does adding 0.01 improve rounding here? thanks.

This might be a very simple function, but it's basically unreadable. Makes maintaining a codebase a lot harder. Same function just with more descriptive variable names and a comment or two and you should be set.

Shorter does not always equal better.

Hint: dont waste your time on it

how stupid is this logic.
after 2 undo and 2 redo x should equal 50.
why it is not like this?

Im very new to javascript so my solution is terribly ugly compared to this. Can you explain how yours is working? I don't even know where to start.

How to round it in JS ??
