Hello World

In notebook:

JavaScript Fundamentals Node JS
Video Course on Real-Time HTML5 with Node.jsjust ​console.log("hello world");

the javascript engine (V8) does not know what IO even means
what makes Node special that it creates a hosting envrionment for the JavaScript, like a browser. It extends JavaScript with extra capabilities, like filesystem, IO, etc.

it's NodeJS that adds ​console.log​ 

​process.stdout.write("Hello World")​ is the same but at low level (doesn't work on my computer)

​console.log​ is actually a ​writeln​ 

maps to linux semantics
