// Problem 5: File Extension Checker

// Problem Statement: Create a function checkFileExtension(filePath, expectedExtension) that takes a file path and an expected file extension as input. The function should check if the file has the expected extension using the path module and print the result to the console.

const path = require('path');

function checkFileExtension(filePath, expectedExtension) {
    // Extract the file extension from the file path
    const actualExtension = path.extname(filePath);

    // Check if the actual extension matches the expected extension
    if (actualExtension === expectedExtension) {
        console.log(`File has the expected extension: ${actualExtension}`);
    } else {
        console.log(`File does not have the expected extension. Expected: ${expectedExtension}, Actual: ${actualExtension}`);
    }
}

// Test Cases

checkFileExtension('test-files/file1.txt', '.txt');
// Expected Output: File has the expected extension: .txt

checkFileExtension('test-files/image.png', '.jpg');
// Expected Output: File does not have the expected extension. Expected: .jpg, Actual: .png
