We can reorder arrays with JavaScript with destructuring.
For instance, we can write:
const swapPositions = (array, a, b) => {
[array[a], array[b]] = [array[b], array[a]]
}
const array = [1, 2, 3, 4, 5];
swapPositions(array, 0, 1);
console.log(array)
We create the swapPositions array with the array to reorder, and the a and b parameters which are the indexes of array items to swap.
In the function body, we swap the position of the elements with indexes a and b by putting them both in an array and then destructuring them.
This will swap the 2 array items in place.
Therefore, when we call swapPositions with array , 0, and 1, we get:
[2, 1, 3, 4, 5]
as a result.
