Copy and modify
(IDE etc.)
Examples: VSCode, Notepad++ or regular notepad
Web browser like Google Chrome or Mozilla Firefox
In VSCode, you can just write ! and it will autofill the setup for a html file.
If you don't use VSCode or it does not work, you can copy this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
</body>
</html>You can create a javascript file in many ways. You can for example create any type of file in your folder/working directory and end it with .js. This can easily be done in VSCode where you can clearly see the file extention (what the file ends with after .).
<body>
<script src="filename.js">
</body>Open the console by either pressing f12 while in the browser or opening though right-clicking and choosing "show console".
