What is Nodejs?
Node.js was released in May 2009 and developed by Ryan Dahl. It is a JavaScript runtime environment based on the Chrome V8 engine. It uses an event-driven, non-blocking I/O model to allow JavaScript to run on the server-side development platform.
Simply put, Node.js is JavaScript running on the server. If you are familiar with Javascript, then you will easily learn Node.js.
Nodejs usually uses the command npm install xxx
to install third-party packages, which requires us to install the npm tool, similar to the pip tool in python.
Install or update nodejs and npm
Run the following commands to install and update nodejs and npm.
sudo apt-get update
sudo apt-get install nodejs
sudo apt-get install npm

Then check the current Node version with the following command.
