Node.js
Let’s gain a better understanding of the nature of Node.js and it’s building blocks.
We'll cover the following...
Node.js is a popular, cross-platform, and open-source JavaScript runtime environment used to create server-side applications. It’s supposed to be used outside the browser context, so it doesn’t support the browser-specific JavaScript APIs, but it adds more support for more traditional operating system APIs, like file system APIs. Node.js is JavaScript code that uses an event loop.
Why Node.js?
We have listed a few points below to explain why Node.js is a good choice to get started with back-end development:
-
It’s fast! That’s because Node.js runs Google Chrome’s V8 JavaScript engine outside the browser. It gives a great performance because it’s designed to optimize throughput and scalability, an important factor in streaming and real-time applications. That’s why it’s used by Netflix, PayPal, and Uber.
-
It uses plain JavaScript so millions of JavaScript developers can now write server-side and client-side code without learning completely different ...
