Node.js

Windows
MacOS/Linux

Download Node.js LTS from the official website. We recommend you to use the LaTest Stable version of Node (also called the "LTS" version). Currently, it is the 16.15.0 version.
Install Node.js by clicking on the executable you just downloaded.

Install fnm to manage multiple node versions:
- follow the official instructions
Copy-paste the commands given at the end of the installation script into your .bashrc or .zshrc file.
Activate the --use-on-cd config to automatically use the correct version on each project:
- In the commands you pasted in your .bashrc or .zshrc file, replace
```
eval "$(fnm env)"
```
  by
```
eval "$(fnm env --use-on-cd)"
```

Now, check that the installation was successful:

Open a terminal and run node -v, and then npm -v.
You should get a version number for each command. If you get an error such as command not found, the installation did not work. You can also have to restart your computer to make it work.

As you saw, node.js comes with two different commands:

node is the programming language itself, which allow us to run scripts in javascript
npm is the node package manager, which we will use to install dependencies
