Javascript comparing array

1

Hello there ! :slight_smile:

Someone can tell me why this is false

const ab = ["a","b"]

const ba = ["a","b"]

console.log(ab === ba)

two object instances will never be equal. you sould use, first a comparison of length and after that go throug each element i compare them.

if(JSON.stringify(ab)==JSON.stringify(ba)).
