Node JS moves to the next request even before a process completes thanks to its non-blocking event-based system. This is a great thing for web-based applications and any other system that benefits from real-time communication.
As previously mentioned, Node JS enables handling multiple requests at once with ease thanks to its single-threaded event looping system. Node JS uses a single-threaded program that provides services to a very large number of requests, making it better than a server like Apache HTTP.
Many enterprises use Node due to its good relationship with microservices. Being microservices-based means that it is divided into smaller and independent pieces (or services) and that each service is designed to do a certain task efficiently. Microservices are highly scalable, as they allow programmers to add or remove features without interfering with the existing ones.
For example, if you were to make a game, you could code it to keep track of player stats in real-time, implement a chat for players to communicate, stream video or audio, and also handle the online multiplayer part of the game.
To start using Node JS, you should first download it on its official website. After you’ve done that, you might want to follow a basic guide also found on its official website. This guide will give you an example of how Node JS works using a single basic app as an example.
And in case you’re interested in developing more advanced applications using Node JS, its website also offers an introductory course that will give you a detailed explanation of each of its components.
