How to install NodeJS 12.x on Ubuntu in 1 minute

Run these shell commands on your Ubuntu computer to install NodeJS 12.x:

curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs

Instead of setup_12.x you can also choose other versions like setup_8.x. However, using this method, you can’t install multiple versions of NodeJS in parallel.
