3. Node.js

Node.js is an Javascript Open source runtime environment. It is built on the Chrome browser’s V8 engine. Without a separate runtime environment, JavaScript can only be run using the environments of browsers. But Node.js enables JavaScript to be used as a standalone scripting language, like Python.

Developers can now test JavaScript on their own machines, instead of having a browser do it for them. This extends the capabilities of JavaScript from only making websites more interactive to just about anything.
