Learn NodeJS Step by Step

Node.js is a compelling JavaScript-based platform that's built on Google Chrome's JavaScript V8 Engine.

It is used to develop I/O intensive web applications, such as video streaming sites, single-page applications, online chat applications, and other web apps.

Large, established companies and newly-minted startups alike (Netflix, Paypal, NASA, and Walmart, to name a few) use it often. Eager to know more? This tutorial will help you in getting started with node.js. Node.js is open-source and completely free, and thousands of developers around the world use it.

The platform brings plenty of advantages to the table, making it a better choice than other server-side platforms, like Java or PHP. Start Learning With Our FREE CoursesEnroll Now. First, we'll go through some of the basic concepts required in getting started with node.js, and then we will create our own Weather App.

This application will enable us to search for weather conditions anywhere in the world. Let us now begin our tutorial on NodeJS by understanding what is node.js.

Node.js is an open-source, cross-platform JavaScript runtime environment and library used to run web applications outside the client's browser. Ryan Dahl developed it in 2009, and the latest version, v13.8.0, was released on Jan.

Node.js is used to create server-side web applications and is perfect for data-intensive applications since it uses an asynchronous, event-driven model. Fig: Node.js logo. Now that we have learned the basics of getting started with node.js, let us next learn the architecture of node.js.

Node.js Tutorial for Beginners: In this Introductory Tutorial of Node.js you will Learn:.

What is Node.js? Prerequisites for Learning Node.js. Why you should Learn Node.js? Node.js - History. Ryan Dahl: is a software engineer and the original developer of Node.js javascript runtime came up with a brilliant idea.

He thought it would be great to execute JavaScript outside the browser means on the Server, so he took Google's JavaScript V8 Engine and embedded with C++ Program and called it Node.

So Node is Runtime Environment for executing JavaScript Code on the Server.

Node js is single-threaded, which employs a concurrency model based on an event loop.

It doesn’t block the execution instead registers a callback which allows the application to continue.

It means Node.js can handle concurrent operations without creating multiple threads of execution so it can scale pretty well.
