What Is Node.js?

Node.js is a back-end JavaScript runtime environment that is open-source, cross-platform, and runs on the V8 engine. It executes JavaScript code outside of a web browser. Node.js allows developers to use JavaScript to create command line tools and server-side scripting, which involves running scripts on the server to generate dynamic web page content before the page is sent to the user's web browser. As a result, Node.js represents a "JavaScript everywhere" paradigm, bringing web-application development together around a single programming language rather than separate languages for server-side and client-side scripts.

Despite the fact that .js is the standard filename extension for JavaScript code, the name "Node.js" does not refer to a specific file in this context and is simply the product name. The event-driven architecture of Node.js allows for asynchronous I/O. These design choices are intended to improve throughput and scalability in web applications with numerous input/output operations, as well as in real-time Web applications.

Node.js was created by Ryan Dahl in 2009, about thirteen years after the release of Netscape's LiveWire Pro Web, the first server-side JavaScript environment. Initially, only Linux and Mac OS X were supported. Dahl was in charge of the project's creation and upkeep, with funding provided by Joyent later on.

When it came to handling many concurrent connections, Apache HTTP Server, the most popular web server in 2009, Dahl bemoaned the limitations of both its limited capabilities and the most common way of writing code, which either blocked the entire process or implied multiple execution stacks when dealing with many simultaneous connections.

Node.js Historic Timeline:

  • The npm package manager for the Node.js environment was released in January 2010 as part of the Node.js release cycle.
  • Microsoft and Joyent released a native Node.js application for Windows in June 2011.
  • Dahl stepped down as project manager in January 2012 and was replaced by coworker and npm creator Isaac Schlueter.
  • Schlueter announced in January 2014 that Timothy J. Fontaine would be in charge of the project.
  • When it was announced that a neutral Node.js Foundation would be formed in February of 2015, everyone was excited.
  • As of September 2015, Node.js and io.js versions 0.12 and 3.3 had been recombined into a single version of Node.
  • There is a new version of Node.js available in February 2016: 0.10.42.
  • The JS Foundation and the Node.js Foundation merged in 2019 to form the OpenJS Foundation.

 

You can see how popular Node.js is by looking at the statistics below...

  • Node.js is 13th most popular framework in top 10k sites worldwide.
  • Node.js is 14th most popular framework in top 100k sites worldwide.

Advantages of Node.js Language for Developers

Node.js has various benefits for developers; a few of the most important benefits of using Node.js are given below.

  • Node.js has fast performance and data processing, highly reusable code, and code that is simple to learn, write, read, and maintain. It also has a large resource library, thousands of free guides, and a vibrant community.
  • Node.js provides a quick environment for developing microservices of any kind.
  • Node.js gives developers an advantage when building a scalable web application. Web application developers can easily scale their apps up and down using Node.js.
  • The Java code is interpreted by Node using Google's V8 Javascript engine. The V8 engine integrates JavaScript code directly into its machine code. It gives programmers the ability to put code into action efficiently.
  • Web developers can exchange data between the client-server and web server using Node.js and JSON.
  • With Node.js, developers can use JavaScript in the runtime environment to build both the front end and back end of web applications.
  • The open-source runtime environment Node.js also offers a caching module. When the application receives a request for the first module, it stores the request in the application's memory.
  • Node.js allows developers to develop apps faster because it is a lightweight technology that is supported by a wide range of tools.
  • With a large and active community of software developers, Node.js is always improving and evolving.
  • Using nob-block I/O systems, the technology is able to handle multiple requests at once.
  • JavaScript is a popular front-end programming language for web applications.

There are several other advantages to learn Node.js and adopt it for your next website or app development project.
