how to use the truncate function from fs-extra in javascript

The fs-extra module provides an easy-to-use wrapper for the Node.js fs module that includes additional file system operations. One of these operations is the truncate function, which allows you to truncate a file to a specified length.

To use the truncate function, first install the fs-extra module by running the following command in your terminal:

npm install fs-extra

Once you've installed the module, you can call the truncate function like this:

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

fs.truncate('/path/to/file', 1024, (err) => {
  if (err) throw err;
  console.log('File has been truncated!');
});

In this example, the truncate function is called with three arguments:

1. The path to the file you want to truncate.
2. The length you want to truncate the file to (in bytes).
3. A callback function that will be called once the operation is complete.

If the operation is successful, the callback function will be called with no arguments. If an error occurs, the err parameter will be set to an instance of the Error class.
