What is the output ?? Var x=12;. Var y+=x;. Console.log (x)

Question

please answer , I don't know the use of log.

Answer 1

the tag is plain wrong it should be JS, javascript, web not c++.
please consider editing your question and adding relevant tags so you get better help and others don't get here by mistake while searching.

Answer 2

12, because console.log only prints the value to the console. y+=x adds the value of x to y, while x stays the same.
there are multiple ways to print to console.
info, log, error, warning to name a few.
these are to help in debugging and filtering the console

Answer 3

I think your tag is wrong ...

Edit : not the case anymore :) (tag was c++)

Answer 4
