Once you download Node, the NPM or Node Package Manager automatically gets installed as it also ships with the node.

Installing the Text Editor

The next thing is to install a text editor which will help you in writing code. The one which I personally use is Visual Studio Code by Microsoft.

You can download it from here: https://code.visualstudio.com/

Once you are done with the text editor, the next thing which you can do is to check whether the path of the Node is correct or not.

Testing Nodejs and NPM installation

You can check your node installation just by running a small node command which will show you the version installed. Just open your cmd or PowerShell and paste the below command. This will show the version of node installed on your computer.

v12.16.0

Similarly, you can check the version of npm installed on your computer. Just paste the below node command to check the version.

v6.13.4
