I'm ready to guide you through the essential aspects of the File System (fs) module in Node.js:

Understanding the fs Module:

It's a built-in module that provides a wide range of functionalities for interacting with the file system, allowing you to read, write, delete, and manage files and directories on your server.
Accessing the fs Module:

To use it in your Node.js project, import it using the require() function:
JavaScript
const fs = require('fs');

Key Methods and Operations:

Reading Files:

fs.readFile(filename, [options], callback): Reads the entire contents of a file asynchronously.
fs.readFileSync(filename, [options]): Synchronous version (blocks execution until reading is complete).
Writing Files:

fs.writeFile(filename, data, [options], callback): Writes data to a file, creating it if it doesn't exist.
fs.writeFileSync(filename, data, [options]): Synchronous version.
Appending to Files:

fs.appendFile(filename, data, [options], callback): Appends data to the end of an existing file.
Deleting Files:

fs.unlink(path, callback): Deletes a file.
Creating Directories:

fs.mkdir(path, [options], callback): Creates a new directory.
Listing Files and Directories:

fs.readdir(path, [options], callback): Reads the contents of a directory (lists files and subdirectories).
Checking File Existence:

fs.exists(path, callback): Checks if a file or directory exists.
Getting File Information:

fs.stat(path, callback): Gets detailed information about a file, such as size, permissions, and modification time.
