How to check if a file or directory exists at a given path using the path package?

To check if a file or directory exists at a given path using the path package in most programming languages, you can use the exists() method or function provided by the path package. Here's an example using Python:

import os

path = "/path/to/file_or_directory"

if os.path.exists(path):
    print("File or directory exists.")
else:
    print("File or directory does not exist.")

And here's an example using Node.js:

const path = require('path');
const fs = require('fs');

const filePath = '/path/to/file_or_directory';

if (fs.existsSync(filePath)) {
  console.log('File or directory exists.');
} else {
  console.log('File or directory does not exist.');
}

The exists() method or function will return True or false depending on whether the file or directory exists or not at the given path.
