Form Validation

Form validation is the process of checking the information entered into an online form to ensure it is complete and correct before submission. It verifies details like email addresses, phone numbers, or dates to prevent errors, typos, or missing data. This helps maintain data quality, enhances user experience by providing instant feedback on mistakes, and protects systems from invalid or malicious input. Essentially, form validation acts as a gatekeeper, ensuring that the information collected is accurate and useful for its intended purpose.
