JavaScript One Line Array Element Swap

Use Object Destructuring to Swap Elements

const arr = [1,2,3,4];

[arr[0], arr[2]] = [arr[2], arr[0]];

console.log(arr);

Explanation

On the right-hand side, we are creating a new array of [3, 1]. We immediately use destructuring assignment to override the values at position arr[0] and arr[2].

It's a good trick to swap elements that I thought I could share.
