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

The accessSync function from the fs-extra package provides a synchronous way to check the accessibility of a file or a directory. Here's how to use it:

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

try {
  // This will throw an error if the file or directory does not exist or is not accessible
  fs.accessSync('/path/to/file/or/directory', fs.constants.R_OK | fs.constants.W_OK);
  console.log('File or directory is accessible.');
} catch (err) {
  console.error('File or directory is not accessible.');
}

In the code above, we require fs-extra and then try to access a file or directory at the specified path. The second argument is a bit mask indicating the accessibility mode we want to use. In this case, we use fs.constants.R_OK and fs.constants.W_OK to check if the file or directory is both readable and writable. If an error is thrown, we log an error message indicating that the file or directory is not accessible.

Note that accessSync is a synchronous function, so it will block the execution of your code until it finishes checking the accessibility of the file or directory.
