benchmarking is the only way to find that out.

I think a solution for maximum performance would look quite different and would be significantlyfaster (10x to 20x faster i would totally guess). Usually regular expressions are only faster if your programming language is not so performance (like early perl/php implementations I guess).

This was a million years ago, but I'm wondering about the performance of this solution. It's certainnly very readable and elegant once you know a little about regex. Are there multiple iterations involved? How does that work under the dashboard?

what the heck ... clever!

wow

Nice

Hmm, regex is always cool, much like an epigraph 🤔.bt clean.

I didn't even think of using a map. Was so focused on iterating through the array and working with a string it didn't even occur to me. Tunnel vision.

Very hard for beginner!

What's funny is that the better solution is the one nobody talks about

This is the best solution. Nice.

never thought of using regEx like this. its actually pretty cool !

it's a fluke, it does not work with Number.MAX_SAFE_INTEGER

I essentially did the same code but declaring arrays and variables. This is much smoother !
