Ćwicz JavaScript
Javascript.info and https://www.tutorialspoint.com/javascript/index.htm are awesome
sites for learning Javascript!
For practice, go to https://www.w3schools.com/js/tryit.asp?filename=tryjs_myfirst and
copy/paste this and you're good to go:
<!DOCTYPE HTML>
<html lang="en">
<head>

<meta charset="UTF-8">

/* Styling */
