React Forms Explained: Controlled Components, Validation, and React Hook Form

Day 24 of the React Mastery Series covers how to build and manage forms in React, a skill considered essential for frontend developers. The article contrasts controlled components, where React state drives input values, with uncontrolled components that rely on the DOM directly. It demonstrates how grouping multiple fields into a single state object improves scalability over managing separate state variables for each input. React Hook Form is introduced as a library that reduces boilerplate code and minimises re-renders, making it better suited for large forms with many fields. The piece also touches on schema-based validation using Zod, which allows developers to define and centralise validation rules in enterprise-grade applications.
