Install Node.js (JavaScript Virtual Machine and Runtime)

We use Node.js as the JavaScript environment in this course. Node is based on Google's V8 JavaScript virtual machine.

Install node. You're free to install it in whatever way you want.

If you have other contexts in which you need possibly different versions of node, you may want to use nvm (Node Version Manager) to install and manage multiple different versions of node on your machine. You can install nvm e.g., by using Homebrew. Of course then you first have to install Homebrew. (If you develop software on a Mac, chances are high you already installed Homebrew.)

Which version of node are you running?

Run node --version to find out, and copy its output here:

Install JDK (Java Virtual Machine and Compiler)

There now is the commercial and the open version of JDK. We recommend to get the open version (called Open

JDK).

We will use Java 21 or later in this course. You can find the Eclipse Temurin distribution at adoptium.net.

What is the output of java --version after installing the JDK?

Install Git

You probably already have Git on your laptop. To verify that you have it, open a Terminal and run git --version.

If you don't have Git, install the one from Apple if you use macOS (the above command probably tells you how to install it).

What is the output of git --version after installing Git?

Which version of the V8 JavaScript virtual machine does your node use?

Run node -p process.versions.v8 to find out, and copy its output here:

Your GitHub Account

First, you need a GitHub account. Create one on github.com if you don't already have one.

Enter your GitHub username here (e.g., my username is hauswirth):
