Node.js is an open-source, cross-platform runtime environment for developing server-side networking applications. Node.js uses an event-driven, non-blocking I/O model which makes it lightweight and efficient. The platform provides lots of ready to use modules which helps to simplify the development process. One of the best perks about node.js, though, is its brilliant use of asynchronous programming.

Asynchronous Programming

With any other language, waiting for requests can be a time-consuming task. Using node.js with its asynchronous abilities has eliminated waiting for a request by merely moving on to the next request with ease. This also makes node.js efficient for memory because it runs a single-thread, asynchronous, non-blocking process.

Uses

Node.js can wear lots of hats for its many abilities. It is very good with files and has the built-in ability to create, open, read, write, delete, and close files on the server. It is also valuable for working with databases and knows how to add, delete, and modify data in databases. Furthermore, node.js has the ability to collect form data and can be programmed to store or manipulate that data. Finally, as all good frameworks should do, node.js has the ability to generate dynamic page content.
