- Go to node website https://nodejs.org/en/

- In my pc node was installed before which is 10.16.3 but you can install 12.13.1 (LTS Recommended For Most Users) because LTS means Long Term Support
- Download and install
- Now open command promt and write
node --v
then you’ll see what version use are using of npm.

- create a folder and name it whatever you want

- create a file and name it whatever you want with .js extention

- Write the simple code in there

- Open command promt on this folder and write command
node YOURFILENAME
likenode app.js

And magic!!! see the result!

So can you install the node right now ?
