Client-side validation improves user experience by catching errors early, while server-side validation ensures data integrity and security.
What are some common validation techniques I should implement?
Common techniques include regex for format validation, range checks for numerical values, and required field checks to ensure necessary data is provided.
How can I handle validation errors effectively?
You can handle validation errors by displaying clear messages next to the input fields, highlighting the fields with errors, and allowing users to correct them easily.
