How can I reverse an array in JavaScript without using libraries?

Question

I am saving some data in order using arrays, and I want to add a function that the user can reverse the list. I can\'t think of any possible method, so if anybo

Answer 1

Reverse by using the sort method

• This is a much more succinct method.

const resultN = document.querySelector('.resultN');
const resultL = document.querySelector('.resultL');

const dataNum = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
const dataLetters = ['a', 'b', 'c', 'd', 'e'];

const revBySort = (array) => array.sort((a, b) => a < b);

resultN.innerHTML = revBySort(dataNum);
resultL.innerHTML = revBySort(dataLetters);
