Node.js is built in a way that helps it work really well and fast, especially when it deals with tasks like reading or writing files. Let's explore this in simple terms.
Node.js uses a special method called non-blocking I/O. This means that when it gets a request, it doesn’t just sit and wait for that task to finish. Instead, it keeps working on other tasks at the same time.
For example, if someone asks to read a file, Node.js will start that process but won’t stop everything else. It can still help other users while it waits for the file to load.
The event loop is a key part of how Node.js works. It helps manage tasks that happen at different times, which are called asynchronous callbacks.
When Node.js has a task to do, like reading a file, it doesn’t get stuck. The main part of Node.js keeps going, and when the file is ready, it puts that info in a line to be processed later, once everything else is done.
This way of working makes Node.js very scalable. It means that many users can send requests all at once without slowing down the server.
So, Node.js can handle thousands of connections at the same time. This is especially great for things like chat apps and live streaming, where lots of people are using the service together.
To sum it up, Node.js is really efficient because it uses a single-threaded model along with non-blocking I/O. This means it makes the best use of resources and can deliver quick responses!
