rename a directory in javascript

To rename a directory in JavaScript, specifically in Node.js, we can use the fs module (file system) which provides many useful methods to interact with the file system.

Here is an example code snippet that uses the fs.rename() method to rename a directory:

index.tsx
const fs = require('fs');

const oldDirName = './old-directory-name';
const newDirName = './new-directory-name';

fs.rename(oldDirName, newDirName, (err) => {
  if (err) {
    throw err;
  } else {
    console.log('Directory renamed successfully!');
  }
});

In the code above, we first require the fs module which provides the rename() method. We then define the old and new directory names as variables.

The fs.rename() method takes three parameters: the current name of the directory, the new name to give the directory, and a callback function to handle any errors.

When the method is executed, if there are no errors, the callback function will be executed, and a success message will be logged to the console. If there is an error, the throw err statement will be executed, and the error will be logged to the console.
