Node.js is open source and cross-platform, meaning that applications built using it can run on Microsoft Windows, Mac OS, and Linux. Node.js also has an extensive library of JavaScript modules to simplify the development process.

Since its development in 2009, Node.js has grown into a reliable environment with many active users. If you learn Node.js , you’ll be able to develop fast and scalable network and online applications. It makes use of an efficient and straightforward input-output (I/O) model, which makes it perfect for real-time and data-based web applications.

What Are the Advantages of Node.js?

  • Scalability: One of the biggest benefits of Node.js is its scalability. You can easily scale an application across multiple servers or increase its performance by scaling it into a single dedicated server.
  • Full stack applications: Although Node.js is usually used for backend application development, it can also be applied to the front end. Therefore, it’s possible to build a full app using only Node.js.
  • Product development: On most platforms, it isn’t easy to build an application from start to finish. However, Node.js technology gives developers more freedom when it comes to development.
  • Easy to learn: Since most web and app development teams are already proficient in JavaScript, it’s easy for them to apply their software engineering expertise to learn Node.js quickly.
  • Speedy: Node.js uses non-blocking I/O systems. This helps developers manage many requests concurrently. The requests are also executed quickly, systematically, and accurately.

Top Apps Built With Node.js

Apps have become the go-to technology for many businesses, and a good user experience is an important part of making sure an app is successful.
