Take an Array
Suppose, we have a array
numbers that contains 5 numbers:
const numbers = [1, 2, 5, 4, 3];
We want to swap index two  with index four . We can do it in wo ways.
This is the easiest way to swap elements:
const numbers = [1, 2, 5, 4, 3]; [numbers, numbers] = [numbers, numbers]; console.log(numbers);
We don’t need to take any temp array to do this.
We can swap in another way. In this way, we need to take a temp array. Let’s see the example:
const numbers = [1, 2, 5, 4, 3]; const temp = numbers; numbers = numbers; numbers = temp; console.log(numbers);
In the console, we will see the output like:
That’s it. Thanks for reading. ?
[1, 2, 3, 4, 5]
