Whether you're a beginner or an experienced developer, this book is your key to mastering Node.js and building efficient backend systems. Node.js is an open-source, server-side jаvascript runtime environment that allows you to execute jаvascript code outside of a web browser. It was created by Ryan Dahl in 2009 and has gained significant popularity among developers since then. Traditionally, jаvascript was mainly used for scripting client-side behavior in web browsers. However, Node.js introduced the ability to run jаvascript on the server-side, enabling developers to build scalable and high-performance network applications. It uses the V8 jаvascript engine, developed by Google for the Chrome browser, to execute jаvascript code. Node.js provides an event-driven, non-blocking I/O model, which means it is capable of handling many simultaneous connections efficiently. This makes it well-suited for building real-time applications, such as chat servers, streaming services, or applications that require high concurrency. It also has a vast ecosystem of packages and modules available through the Node Package Manager (npm), which makes it easy to leverage existing libraries and frameworks. One of the key advantages of Node.js is its ability to handle I/O operations asynchronously, using callback functions or Promises. This approach allows developers to build highly performant applications that can handle a large number of concurrent requests without blocking the execution flow.
