rename a json file in javascript

To rename a JSON file in JavaScript, we need to use the File System module in Node.js. Here's how you can rename a JSON file:

index.tsx
const fs = require('fs');
const oldFileName = 'old_file.json';
const newFileName = 'new_file.json';

fs.rename(oldFileName, newFileName, (err) => {
  if (err) throw err;
  console.log('File renamed successfully');
});

Explanation:

1. First, we require the fs module in Node.js.
2. We specify the name of the old file and the new file.
3. We use the rename() function provided by fs module to rename the file. The first parameter is the current file name, the second parameter is the new file name, and the third parameter is a callback function to handle errors (if any).
4. If there are no errors, the callback function will execute and a success message will be logged to the console.

Make sure that you have the necessary file permissions to rename the file.
