There are a few ways for you to run JavaScript on your computer. These are the main two ways.
- Browser (Chrome, Safari, Edge)
- In your Terminal or Command prompt using Node.JS
Running custom JavaScript in your browser
The easiest way to do this that I know of, is you can create a file on your computers desktop. Like this.
Open a text editor, like Notepad, or Visual Studio Code. https://code.visualstudio.com/
Save a file that looks like this.
<html>
<head></head>
<body>
<p>Your own webpage, with a JavaScript popup!</p>
</body>
<script>
window.alert('Hello World");
</script>
</html>You can make this file using a text editor to make a .html file.
This one is example.html
Running JavaScript from the command line

The LTS means long term support, and is a great version to start out with.
Once you have it installed, create a file, and open up a terminal to run it.
If you’re using visual studio code, you can do that here. It looks like this.
