In the realm of server-side JavaScript, Node.js stands tall as a powerhouse for building scalable and efficient applications. One of its key features is its non-blocking I/O model, which allows handling file operations asynchronously.
In this article, we’ll delve into the world of Node.js File I/O operations and explore how callbacks can streamline your code, making it more manageable and responsive.
Understanding Node.js File I/O Operations
File I/O operations in Node.js involve reading from and writing to files asynchronously. This means that while one operation is being executed, the program can proceed with other tasks without waiting for the file operation to complete. This asynchronous nature is what makes Node.js highly efficient, especially for I/O-bound tasks.
Traditionally, handling asynchronous operations in JavaScript has been a challenge due to its single-threaded nature. However, Node.js provides a solution through callbacks, which allow you to specify what should happen once an asynchronous operation completes.
