Several options are available for installing Node.js; using virtual environments (conda) is recommended for isolation, then it is advised to use a package manager to keep up to date with the latest versions, and finally, it is possible to install from an executable:

1. First, Node.js should be installed using conda, or the Anaconda Navigator. This is the recommended process as nodejs will be isolated from the rest of the system. This prevents unnecessary conflicts between dependencies. To install with conda, run the following command:

conda install -c conda-forge nodejs

2. Package managers will install Node.js globally on a machine with the help of the following commands:

On Windows, you can do it via Chocolately:

cinist nodejs.install

If you are using macOS, you can also use Homebrew to install Node.js with the help of the following command:

brew install node

If you are using a Debian-based system, then use the following command:

# Using Ubuntu
curl -sL https://deb.nodesource.com/setup_13.x | sudo -E bash -
sudo apt-get install -y nodejs

# Using Debian, as root
curl -sL https://deb.nodesource.com/setup_13.x | bash -
apt-get install -y nodejs

Otherwise, for more information, refer to the Node.js website (https://nodejs.org/en/download/package-manager/).

3. Finally, on Windows and macOS, it is possible to download and install Node.js directly from the official website (https://nodejs.org).
