Writing Clean & Maintainable Code

Which code demonstrates better error handling practices in JavaScript?

// Option A:
function processData(data) {
  try {
    // Process data
  } catch (error) {
    console.log('Error:', error);
  }
}

// Option B:
function processData(data) {
  try {
    // Process data
  } catch (error) {
    if (error instanceof ValidationError) {
      handleValidationError(error);
    } else if (error instanceof NetworkError) {
      handleNetworkError(error);
    } else {
      logError(error);
      throw new ApplicationError('Data processing failed', { cause: error });
    }
  }
}

Option A because it's simpler
Option B because it handles errors more specifically
Option B demonstrates better error handling practices because it: 1) Differentiates between different types of errors, 2) Handles each error type appropriately, 3) Maintains the error chain by including the original error as the cause, and 4) Provides more meaningful error information. This approach makes debugging easier and helps maintain application stability.
Both are equally good
Neither demonstrates good practices
