thanks!
I love it too

The name is repeatStr. It's called arrow function expression. It's missing const or let tho.

how does it work with no function name initializated ?

I can't understand it🤔

hey, a familiar face!
have I help you a long time ago with your travian tools?
honestly, I can't remember a thing, except it was fun )

10 years ago I was also saving each extra loop iteration, making code better as I thought. That's called premature optimiztion and highload is about scalability rather than constant time factor.

two passes through the string characters instead of one, two unnecessary arrays and comparison you don't need
you should try to work with highload, it will give you whole new perspective )

To make the soulution shorter.

Beautiful. This is my favorite one.

nice one!
