A comparaison between 2 equal variables returns false in Google script (sheets)

Question

I hope you can help me in this mind blowing problem I have:

Well, I have 2 different arrays (cam and existentes). The [2] value of existentes is the same string than the 1 value of cam. But when I try to compare existentes [2] == cam [1] it returns a False.

Answer 1

Solution:

You are comparing two arrays : [Remarketing] == [Remarketing] while you should be comparing two strings Remarketing == Remarketing :

existentes[2][0]==cam[1][0]

Minimal Reproducible Example:

 const ar1 = ["Remarketing"]; const ar2 = ["Remarketing"]; console.log(ar1==ar2); // returns false console.log(ar1[0]==ar2[0]); // returns true

In case you had arrays with multiple elements you wanted to compare, then you can read this post on how to compare two arrays in JavaScript :
