How to start a script/app in node.js?

Question

If I type console.log('Hello World'); in node.js it works, I get the "Hello World" message back.

But if I make a "helloworld.js" document with console.log('Hello World'); inside and then type "node helloworld.js" in node then nothing happens.

I have tried placing the script in same folder as node.js but still doesn't work.

Make sure that you're not running Nodejs.exe because that is the REPL .

Instead you should open a regular Command Prompt window ( cmd.exe ) and run the command

node helloworld.js

Make sure you run this command in the directory where the js file exists, the node application path is mapped in your environment settings.
