How does fs.rename work?

fs.rename is a method in Node.js that is used to rename a file or folder asynchronously. The method takes two parameters - the current path of the file or folder and the new path that it should be renamed to. If the new path already exists, the method will replace it with the renamed file/folder.

const fs = require("fs");

// Rename the file "oldname.txt" to "newname.txt"
fs.rename("oldname.txt", "newname.txt", (err) => {
  if (err) throw err;
  console.log("File renamed!");
});

In this example, the fs.rename method is used to rename the file named "oldname.txt" to "newname.txt". The method takes three arguments: the current file name, the new file name, and a callback function to be called once the operation is complete. The callback function can be used to handle any errors that occur during the operation.
