Why is Node JS so Fast?
Node.js is an event-driven architecture, meaning that it works by responding to events. As opposed to traditional web servers, which execute code in a linear fashion, Node.js code is executed in response to events. This means that it can process multiple requests concurrently, as well as respond quickly to requests. This is because Node.js is able to process requests without having to wait for the next instruction to be executed.
Non-blocking I/O Model
Node.js uses a non-blocking I/O model, which means that it can process requests without waiting for input/output operations to complete. This model allows Node.js to process multiple requests simultaneously and make more efficient use of system resources.
Node.js is a single-threaded programming language, meaning that it can only process one request at a time. However, this does not mean that it is slower than other programming languages. In fact, Node.js is able to process multiple requests simultaneously by utilizing the event-driven architecture.
Node.js uses asynchronous programming, which means that it is able to process requests without waiting for them to complete. This allows Node.js to process multiple requests concurrently and quickly respond to requests.
