Node.js refers to an open source JavaScript runtime that has been solely engineered on a JavaScript engine that is used to develop servers and other network applications. This run-time essentially compiles and then executes JavaScript on its own. The Node.js can be run on OS X, Linux, and Microsoft. Some of the applications written using Node.js are static file servers, web application frameworks, messaging middle ware and servers for HTML5 multi player games just to mention but a few.

It is an application that comes in handy especially in the creation of websites. This is because it has a uniquely sophisticated language that makes it very fast. Therefore, computer windows rarely experience unnecessary drag during a function. In addition to this, Node.js can carry out a lump sum amount of instructions in a single instance. 

This open source JavaScript run-time reduces unnecessary mismatches between two programming events. This is because, with the help of JavaScript, two programs can communicate with each other in real time so as to avoid any issues. With Node express.js, there is enhanced control over the sever by the client meaning that there is zero room for mistakes.

​

Also, it allows for code re-use. With Node.js, one can essentially use any piece of code. There are no limits when it comes to Node.js. It can be manipulated to carry out any tasks and achieve any form of result. For instance, an individual can create real-time website applications by the use of the Node.js. Other uses include the development of APIs that are I/O driven and essentially created so as to handle a lot of instructions at a go. Most stream applications have also been made through the use of the open source JavaScript run-time.

​

Its simplicity enables a developer to plan for his design that is meant to solve a broad spectrum of issues. With Node.js tutorials, there are not so many expenses that are incurred. This is because testing and deployment through the use of pay as you grow services is relatively cheap. Topping the list is the capacity of the Node.js code to accommodate a diversity of platforms with the most ease.

​

Finally, Node.js is easy to maintain. This ensures that no unnecessary strain is put on its users. Therefore it has helped transform the coding world thus guaranteeing the world a better future. Technology cannot advance in its absence thereby making it an essential part of the people's lives in the modern age.
