5 Reasons Why Node.js is Compulsory to Become a Web Developer

March 16, 2020

To become a web developer, you have to choose between two types of languages. These languages include JavaScript, HTML, angular, etc. All of these are client-side languages. Whereas, server-side languages include PHP, C++, Python, etc. Between all these languages, Node.js slowly came into the limelight because of its efficiency and easy to use functionality. The introduction of Node.js has made the work for developers a bit easy and fast.

What is Node.js?

Node.js is a JavaScript runtime environment that is used for developing a server-side application. It enables the user to make the changes in the back-end of any application. Node.js helps in reducing the idle time of the CPU, making it more efficient.

Usually, when a request is sent to the server, then until server processes and gives a response to that request, it can’t handle another query. This is an asynchronous process that is time-consuming and inefficient.  With the introduction of node.js, you don’t have to wait to submit another query. It simultaneously runs processes in a loop, which is known as the event loop. Despite JavaScript being single-threaded, the event loop enables node.js to perform non-blocking I/O operations. The event loop helps node.js to carry out a number of processes at the same time. This makes node.js very useful for highly scalable sites.

Node.js uses single threading to process requests. This helps in saving a lot of memory and high computing speed. It is quite compatible with cloud services. It is very powerful and fast and is used for mobile application development, game development, web development, etc.

5 Reasons to learn Node.js for every Web Developer

#1 Simple to use


JavaScript is the simplest language to learn and the best part of Node.js is that it uses JavaScript to run applications on both server-side and client-side. It is built on Google’s V8 JavaScript engine; it compiles source code into machine code. It is one of the main reasons that make JavaScript so functional.

#2 Job Opportunities

job opportunities

Node.js is one of the most popular JavaScript frameworks used by a lot of developers. The reason behind it is that you don’t have to know various languages for full-stack development. You can simply use it for both back-end and front-end. Many big companies like Netflix, Linkedin, Walmart, Trello, Uber, Paypal, Medium, eBay and NASA are using it because of its unparalleled scalability and less developing time. With the increased demand for Node.js, there have been a lot of career opportunities in this field now.

#3 Productivity


Node.js helps developers save a lot of time. This makes it much more efficient. You don’t have to wait for a single query to resolve. Instead, all your queries will be resolved simultaneously. As it is based on Google’s V8 engine, it makes the processes very fast.

#4 NPM


NPM stands for Node package manager. It helps in providing a better experience to the developers and that is the reason it is updated more frequently. As we know, Node.js is an open-source JavaScript runtime, so with the help of NPM, you can access the codes developed by someone else to handle any particular issue in your project. It is like a library through which you find and use a number of codes from thousands of developers all over the world.

#5 Versatility

applications of nodejs

Node.js is said to be versatile because of its functionality, which is helpful in a variety of applications. Some of the examples are mentioned below:

  • –   Internet of Things (IoT)
  • –   Chat apps
  • –   Single Page Applications (SPA’s)
  •   Collaboration tools
  • –   Streaming based apps
  • –   Microservices
  • –   E-commerce sites
  • –   Project Management


These were some important reasons why Node.js is important to learn. It is one of the most popular technology in recent times and with increased job opportunities in this field, it is no brainer that why you must learn it.
