 * You need sometimes to format you number and one of the common way to format them is to add a leading zero
 * to numbers less than 10. There is many ways of doing this so let me show you some of them.
 *
 * Example:
 * I have a number and I want to prepend a 0 to it if it's less than 10.

 * The idea is to get a random node/entry from a given array.

 * Methods like `querySelectorAll()` are handy to select multiple DOM elements at once.
 * But these methods return a `NodeList` which is a list of all the matching DOM elements.
 * No problem at first glance but when you dig a little bit you'll notice there are some
 * issues when you want to manipulate them.
