is anyone teach me how write a programe in node js

Writing a code in C is quite different from writing a code for Node.
there ain't much dependencies , unlike C , there is no need to include header file/package just for basic coding.

You need to download & install NodeJs from https://nodejs.org/en/download/ . While installing, it will give you an option to add Node to your enviroment variables, you need to selct it.

After installation , open command prompt and type "node --version" , it will print the node version installed. If not, then there must be some issue with the installation.


On successful installation, just open command prompt, move to the location where you want to write your code, create a file "xyz.js", and write the following code :

console.log("It's my first Node Code")

after saving, write Node xyz in cmd and hit enter.
you'll see "It's my first Node Code" written on the cmd. 

Now you can move further with Node.
