Node Ecosystem

How would you describe Node to a non-technical friend?

Node runs in the browser. Node is event-based, meaning that as soon as Node starts its server, it simply initiates its variables, declares functions and then simply waits for event to occur. Node is non-blocking and asynchronous, meaning the program that does not block the execution of further operations. Non-Blocking methods are executed asynchronously. Asynchronously means that the program may not necessarily execute line by line. This is where the event loop comes into play.

What does it mean that Node is a JavaScript runtime? Javascript runtime refers to where your javascript code is executed when you run it. In my case , since I’m using Google Chrome, my node javascript runtime is the V8 Engine.

What is Node used for? Node lets one run JavaScript in the browser. It also has a bunch of built in tools and features that make modern web apps function. Node manages the different tasks, and passes them to the event loop accordingly.
