How Can JavaScript Handle File I/O on Both the Server and Client Sides?

File Handling with JavaScript: Unveiled

JavaScript, a ubiquitous programming language, offers a robust mechanism for reading and writing files. While this is not generally supported within a browser environment, JavaScript's versatility extends to server-side applications.

Server-Side File I/O

To perform file operations server-side, utilize the File class. It empowers you with operations like read, write, and append to files located on the server.

Browser-Side File I/O

The latest versions of HTML5 provide a solution for client-side file handling. This capability allows you to interact with local files using the DND (drag-and-drop) feature.

Node.js File API

Node.js boasts a dedicated File System module that empowers you with a comprehensive set of file operations. Visit the official documentation for an in-depth guide: https://nodejs.org/docs/latest/api/fs.html.
