Client-side validation: The verification of data on the client side of a client-server interaction, usually before the data is sent to the server. This can include ensuring form fields are filled out correctly, input matches expected formats, and other checks. While enhancing user experience by providing immediate feedback, it must not be the sole method of validation due to the potential for bypassing by malicious users; server-side validation provides an additional necessary layer of security.
