Before I explain the benefits of using Node.js in back-end development, let us defined Node.js, it is actually not aframework or library, but a runtime environment, based on Google's V8 JS engine.

For back-end development, some developers prefer Node.js for its speed and because they can use the JavaScript on bothfront and back end. Node.js offers a great package manager, also the number of available open-source tools in npm's registry is massive and growing fast.

The following are just few of many advantages of Node.js that every developer should consider when choosing thetechnology for any project:

Easy Scalability

It is quite easy for developers to scale the applications in horizontal as well as vertical. It's actually easy to add more modules and micro-services on the top of the existing one. Each of these modules can run in its own process.

Easy to Learn

JavaScript is a flexible and powerful programming language; it is extremely popular language among developers andespecially the front-end developers. Therefore, it becomes easier for them to use Node.js in server-side.

Full Stack JS

It called as a full stack JS, because it serves both client-side and server-side applications. Other programminglanguages require two different developers, a front-end and back-end developers. While in Node.js, the things aredifferent, one developer can do both in JavaScript using a runtime environment. This saves lots of time, money andefforts.

Automation

Node.js provides abilities to automate repetitive operations, schedule actions, or share modification records. It canautomatically groups functions and make the code in order.

Wide support

There are many available tools that helps Node.js developers to test their source code, such as Jasmin and other similar tools.
