<h3>What is node.js ? </h3>
- It is known to be JavaScript runtime that is event-driven and asynchronous, making it ideal for creating scalable network applications. In the following "hello world" example, numerous connections can be handled concurrently.
- Every connection triggers the callback, but if nothing has to be done, Node.js will sleep. This contrasts with the concurrency approach that is currently more often used, which makes use of OS threads.
- The utilization of thread-based networking is extremely challenging and wasteful. Node.js users also don't have to worry about deadlocks because there aren't any locks.
- Node.js has almost no functions that conduct I/O directly, therefore the process never blocks until the I/O is carried out using synchronous methods from the standard library.
- Scalable systems can easily be created in Node.js because nothing blocks.
