What are NodeJs :

NodeJs is an open-source cross-platform runtime environment and library for running JavaScript web applications outside the client’s browser. Node JS is used to build fast and scalable server-side and networking applications. It runs on the V8 JavaScript runtime engine, and uses an event-based, non-blocking I/o architecture, making it more efficient and suitable for real-time applications. It is completely free to use.

 

Why do we use NodeJS?

  • NodeJS execution speed is very fast and it runs very fast.
  • You can browse npm (Node.js Package Manager) for over 650,000 free code packages you can reuse with Node.js.
  • There are many JavaScript frameworks but it was always assumed that JavaScript and backend development do not go together. But NodeJs has solved this problem and you can use it as a backend.
  • NodeJS is cross-platform, which means corporate organizations can easily target all major platforms, including Windows, Linux, and macOS.
  • Node JS uses an asynchronous event-driven I/O model that makes it lightweight and efficient.
  • NodeJS is no more scalable than PHP or Ruby. But it is much easier to scale than other backend technologies.

 

Merits and Demerits of NodeJS.

Merits :

  • Easy – node. Getting started is quite easy for js newbies. It’s easy to get started with tutorials and a large community.
  • Scalable –It provides extended scalability for applications. Node.js, being single-threaded, is able to handle a large number of simultaneous connections with high throughput.
  • Speed – Non-blocking thread execution makes Node.js faster and more efficient.
  • Multi-platform –Cross-platform support allows you to build SaaS websites, desktop apps, and even mobile apps using Node.js.
  • Maintainable – Node.js is an easy choice for developers because both front-end and back-end can be managed with JavaScript as one language.

Demerits :

  • Node.js is unable to process heavily CPU-bound tasks, and this is arguably one of the biggest drawbacks of Node.js.
  • Node.js has a large number of packages and modules within the Node package manager. However, NPM lacks a library system, unlike other programming languages.
  • The Node.js asynchronous programming model makes code difficult to maintain.
  • Demand for Node.Js developers is high but experienced Node.Js developers are few and far between.
