rename a file in typescript

To rename a file in TypeScript, you can use Node.js' built-in fs module, which provides a method called rename(). Here's an example:

index.ts
import * as fs from 'fs';

const oldFilePath = 'path/to/old/file.txt';
const newFilePath = 'path/to/new/file.txt';

fs.rename(oldFilePath, newFilePath, (err) => {
  if (err) throw err;
  console.log('File renamed.');
});

In this example, we first import the fs module using the import statement. We then declare two variables: oldFilePath and newFilePath, representing the old and new file paths, respectively.

Finally, we call the fs.rename() method, passing in the old file path as the first argument, the new file path as the second argument, and a callback function as the third argument. The callback function will be executed once the file has been renamed, and will log a message to the console. If an error occurs during the renaming process, the throw statement will catch it and log it to the console.
