Try-Catch-Finally

// Method 1: Basic try-catch
try {
    const result = 10 / 0;
    console.log('Result:', result);
} catch (error) {
    console.error('Error occurred:', error.message);
}

// Method 2: Try-catch with specific error
try {
    const data = JSON.parse('invalid json');
} catch (error) {
    if (error instanceof SyntaxError) {
        console.error('JSON parse error:', error.message);
    } else {
        console.error('Unknown error:', error);
    }
}

// Method 3: Try-catch-finally
try {
    console.log('Trying...');
    throw new Error('Something went wrong');
} catch (error) {
    console.error('Caught error:', error.message);
} finally {
    console.log('Finally block always executes');
}

// Method 4: Nested try-catch
try {
    try {
        throw new Error('Inner error');
    } catch (innerError) {
        console.error('Inner catch:', innerError.message);
        throw new Error('Outer error');
    }
} catch (outerError) {
    console.error('Outer catch:', outerError.message);
}

// Method 5: Error object properties
try {
    throw new Error('Test error');
} catch (error) {
    console.log('Error name:', error.name);
    console.log('Error message:', error.message);
    console.log('Error stack:', error.stack);
}

// Method 6: Custom error handling
function riskyOperation() {
    if (Math.random() > 0.5) {
        throw new Error('Random error');
    }
    return 'Success';
}

try {
    const result = riskyOperation();
    console.log('Result:', result);
} catch (error) {
    console.error('Operation failed:', error.message);
}

// Method 7: Multiple catch blocks (not supported, use if-else)
try {
    throw new TypeError('Type error');
} catch (error) {
    if (error instanceof TypeError) {
        console.error('Type error:', error.message);
    } else if (error instanceof ReferenceError) {
        console.error('Reference error:', error.message);
    } else {
        console.error('Other error:', error.message);
    }
}

// Method 8: Error in async function
async function asyncOperation() {
    try {
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        return data;
    } catch (error) {
        console.error('Async error:', error.message);
        throw error; // Re-throw if needed
    }
}

asyncOperation().catch(error => {
    console.error('Unhandled async error:', error);
});
