NodeJS

To check the installed version of Node.js on your system, you can use the following methods:

Command Line/ Terminal: Open your command line or terminal and type the following command:
```
bash
node -v
```
This will print the installed Node.js version.
```
bash
v14.17.0
```
Additionally, you can also check the installed npm (Node Package Manager) version:
```
bash
npm -v
```
This will print the installed npm version.
```
bash
6.14.13
```
Node.js REPL (Read-Eval-Print Loop): You can also check the Node.js version from the Node.js REPL. Open your command line or terminal and type node to start the REPL. Once in the REPL, type:
```
javascript
console.log(process.version);
```
This will print the Node.js version.
```
bash
'v14.17.0'
```

Choose the method that suits your preference and workflow. The command line option is commonly used and provides a quick way to check the installed version.
