find the parent directory of a directory in javascript

In Node.js, we can use the path and fs modules to work with the file system. To find the parent directory of a directory, we can use the path.dirname() method to get the parent directory's path.

Here's an example:

index.tsx
const path = require('path');
const fs = require('fs');

const directoryPath = '/path/to/directory';

// Get the parent directory path
const parentDirectory = path.dirname(directoryPath);

// Check if the parent directory exists
if (fs.existsSync(parentDirectory)) {
  console.log('Parent directory:', parentDirectory);
} else {
  console.log('Parent directory does not exist');
}

In this example, we first require the path and fs modules. We then specify the path of the directory for which we want to find the parent directory. We then use the path.dirname() method to get the parent directory's path.

We then check if the parent directory exists using the fs.existsSync() method. If it exists, we log the parent directory's path to the console. If it doesn't exist, we log a message to the console indicating that it doesn't exist.
