What is Node.js? A complete guide for beginners, With the complete roadmap

Node.js describes an open-source, cross-platform runtime environment that is based on JavaScript. It is based on Chrome’s V8 JavaScript engine, which reads, interprets, and executes JavaScript code.

Node is speedy and light because it uses an event-driven and non-blocking I/O design. One of the main reasons for the broad acceptance of Node is this programming methodology.

When used as a development platform, Node excels at creating software and services like chat applications and websites that require synchronous, real-time interactions. Its ubiquitous use is partly due to the fact that it also offers a number of other uses and benefits, many of which are well-liked by developers.

Advantages of studying Node.js

JavaScript is easy to learn and uses Node. Most developers are familiar with the popular programming language JavaScript. Even a novice to JavaScript can pick up Node quickly.

Javascript full stack
Full-stack web development was enhanced by Node. One developer may handle the front end, back end, database administration, and other aspects of full-stack web development. Full-stack developers learned several languages prior to Node. Only JavaScript is needed to create front- and back-end web apps using Node.
a market need

Full-stack developers are in need of skills in Node.js. Therefore, including Node.js on your resume might help advance your job as a stack developer. Node.js engineers make $100,000 a year, so it pays nicely.

Freedom in app development
Node offers more flexibility to developers than Ruby on Rails. Node’s straightforward setup enables you to build anything from scratch with minimal restrictions.

Node.js is an open-source framework that is constantly being improved by a vibrant developer community. It makes learning simple as a result.

How does Node.s function?

Node.js was mostly written in C and C++. Because Node.js is software designed to run web servers, it must constantly communicate with the operating system of the device it is running on.

Because Node.js was created using a low-level language like C, it is straightforward for the program to access operating system resources and use those resources to carry out commands.

Node.js’s functioning, however, involves a tremendous degree of complexity. Quick and efficient web servers can be run using Node.js, but how precisely does it achieve this? In this part, you will be guided through the process used by Node.js to achieve its high degree of productivity.

There are three main parts that need to be understood in order to understand how Node.js works. The names of these components are V8 Engine, Libuv, and Event Loop.
