Let’s write some code.

1.lets start By installing Node.js on your system:

https://nodejs.org/en

**2. Verify installed correctly or node by writing command on terminal

node ~v**

The command node -v is used to check the installed version of Node.js. If Node.js is not installed, this command will produce an error indicating that the node command is not recognized or not found

npm ~v

The command npm -v displays the version of NPM (Node Package Manager) that is currently installed on your system.

3.Writing code

• Node REPL [Read, Evaluate, Print, Loop]

   → write command on terminal **`node`**
  

→ You can now write and execute any code on REPL (Read-Evaluate-Print Loop).

• This is all running in a Node runtime environment.
• NodeJS is a JS runtime environment, and behind the scenes, it is using the v8 engine.
• its similar to a browser console.
• We cannot write code like this for a long time; it's frustrating. Let's write code on Vscode or any compiler you like.
