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?

Umm... can anyone explain this solution to me. Srry Im not that sharp hahahahah.

god。。。

Well that killed my code.......

length thing will not work, example the recipe does not have milk, but the available obj does. And I don't think it would be best practice to assume that wouldn't happen, though I don't know if that is true or not.

Cool solution!

After several minutes trying to understand this solution I finally got it. Can't believe its simplicity!

hahaha, you could also reduce it more with let t = this xD

perfect

Easier to read than mine for sure. Kudos! I did write some test cases that caused it to fail though. Not sure if these edge cases are worth handling for a Kata. Testing is in my blood. I'm thinking { mush: 0, apples: 3 }, { apples: 7, mush: 0 } should return 2, { apples: null, mush: 1 }, { mush: 1, apples: 0 } should return 1 and { apples: -1, mush: 1 }, { mush: 1, apples: Infinity } should return 1.
