It's doesn't pass the test.

So short

thank yoooou i couldn't get map to work, I see now i just needed to set questions equal to the new mapped array

Regex is adding unnecessary overhead here

I agree with your statement here, especially when it comes to error handling (although it's not specified in this kata).

The one line solution seems alot more clean and cool but it's definitely not best practice. Thanks for breaking each section down to the nitty gritty.

Very nice but it returns Infinity for empty recipe list. The reduce() method does not execute the function for empty array elements.

I think this is an underrated concern...

But isnt this for a recipe calculation? There's never going to be 100k + ingredients to compare, or whatever you would need for that to make a difference?

nice :D

wow, awsome answer. thxxx
