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

You can use the fs-extra module in Node.js to perform filesystem operations including handling file descriptors. The fs.close method can be used to release the resources allocated by an open file descriptor. The following code shows an example of how to use the fs-extra module to open a file and subsequently close the file descriptor.

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

(async () => {
  const file = await fs.open('./example.txt', 'r');
  // Perform operation on the opened file
  await fs.close(file);
})();

The above code demonstrates the usage of the fs.open method to open a file and obtain a file descriptor. Once the file descriptor is obtained, you can perform any operation on the file. Once you are done with the file, you can release the resources allocated by the file descriptor using the fs.close method. It is to be noted that fs.close is an asynchronous method that returns a promise.
