Command Line JavaScript: NodeJS

NodeJS is an environment that lets you write JavaScript programs that live outside the browser. It provides:

• the V8 JavaScript interpreter
• modules for doing OS tasks like file I/O, HTTP, etc.

While NodeJS was initially intended for writing server code in JavaScript, today it is widely used by JavaScript tools, which makes it relevant to front-end programmers too. A lot of the tools you'll be using in this course leverage NodeJS.
