Handling Errors with try-catch-finally

What error handling practice is shown here?

class ValidationError extends Error {
  constructor(message) {
    super(message);
    this.name = 'ValidationError';
  }
}

try {
  throw new ValidationError('Invalid input');
} catch (error) {
  if (error instanceof ValidationError) {
    // Handle validation error
  }
}

Basic error catching
Custom error types
This demonstrates custom error types: 1) Creates domain-specific error classes, 2) Extends built-in Error class, 3) Enables more precise error handling, 4) Allows for type-specific error handling, 5) Helps organize error handling logic, 6) Improves code maintainability, 7) Enables better error classification, 8) Common in large applications.
