Thanks for the article :)

Tip 11 (Reversing an array) is also modifying the original array colors.

Instead, if I don't want to change the original array, I would write:

var colors = ["blue", "white", "green", "navy", "pink", "purple", "orange", "yellow", "black", "brown"];
var reversedColors = [...colors].reverse();
console.log(reversedColors); // returns ["blue", "white", "green", "navy", "pink", "purple", "orange", "yellow", "black", "brown"]

or colors.slice().reverse() works too
