All Node js version available on below url
https://askubuntu.com/questions/426750/how-can-i-update-my-nodejs-to-the-latest-version

And now we can install Nodejs by below command:
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs

If you had Nodejs before on your machine you need to update NPM (Node package manager), it is an optional command
remember npm comes with Nodejs itself and doesn’t need to install it separately
sudo npm install npm@latest -g

npx create-react-app my-app
