How to swap value in JavaScript

Question

How do I swap value in JavaScript, is it the same as in python with just a = sign or do we still use the old way of temp value? Please help.

Answer 1

We can't do it exactly like Python, but in ES6, this works:
[a, b] = [b, a]

However, since many devices don't support ES6, I'd recommend using a temp. Also, this question has been asked multiple times before. Check out

You're welcome, Leonardo Monterey ! Yes, the search bar is not as good as Google. Sometimes if I don't use the right keywords, nothing useful shows up. But I'm sure the Sololearn team is working on improving it. And I'm sorry I assumed you didn't try searching!

Answer 3

if you’re swapping the values of two variables (x and y) then the general method is create a temp variable, set the value of the temp variable to the value of variable x, set the value of variable x to the value of variable y, set the value of variable y to the temp value.

Answer 5
