Apr 24, 2013 · Here's a one-liner to swap the values of two variables. Demonstration below: b=2, output=document.getElementById('output'); +1. But the shortest version will be in ECMAScript 6: [a, b] = [b, a];.

In this example, you will learn to write a program to swap two variables in JavaScript using various methods.

Apr 2, 2025 · In this article, we will learn about swapping 2 variables with Various Approaches. Here, we will be using a destructing Assignment. The destructing assignment makes it possible to unpack values from an array, object, or other properties into distinct variables. Then we copy the value of B to A (A would be overwritten).

If you really need to achieve the swap, you can use the 2 variables algorithm: you can set a variable outside the scope of the function so you can use it inside the function, this is something you can do: var t = x; x = y; y = t; or even this works.

Oct 12, 2018 · swap(prompt("Enter your first input (this will be your second output):")); swap(prompt("Enter your second input (this will be your first output):")); The swap function goes back and forth between the values 1 and 2 in the variable i. That is how it keeps track of first or second inputs and their exact opposite outputs.
