What is node.js?
Node.js is a software used to develop web applications for servers. It is open-source and runs across platforms. A lot of its basic modules use JavaScript programming language and that is what developers use to write more advanced modules. At runtime, V8 JavaScript engine by Chrome is used to interpret the JavaScript.
Node.js makes use of an event-driven, non-blocking input/output model. NPM, its default package ecosystem contains the biggest open source repository in the world. You no longer need Apache HTTP servers as node.js lets applications act as web servers.
Advantages of node.js
The reasons for the widespread use and popularity of node.js are many. Some of them are listed here.
-
With node.js you use Unix network programming and JavaScript for web development on a virtual machine that is faster than Ruby, Perl, or Python.
-
Node.js can handle a huge number of simultaneous connections on one process with very less overhead.
-
As node.js makes web servers use event-driven programming, they run faster. Servers can be made scalable by using call-backs to notify that a task is completed. This is a very big selling factor.
-
JavaScript programming language is easy to learn and already known by many people.
-
Because JavaScript is used in browsers to respond to events initiated by users and to create interactive effects, it can be easily used for event loops.
-
Because both the web server and browser use JavaScript, there is less impedance mismatch.
