How does graceful-fs.writeFile work?
graceful-fs.writeFile is a method that provides a way to write data to a file using the file system module in Node.js, but with improved error handling and a graceful fallback mechanism in case of an error. It is similar to the built-in fs.writeFile method, but with added functionality to handle errors more gracefully.

Ai Example

const fs = require("graceful-fs"); fs.writeFile("example.txt", "Hello, world!", function (err) { if (err) throw err; console.log("Data written to file"); });
In this example, the writeFile function writes the string 'Hello, world!' to a file named example.txt. The third argument is a callback function that is called when the write operation is complete. If an error occurs during the write operation, it will be passed to the callback function. If no error occurs, the callback function simply logs a message to the console.
