Formik with React #4 - Nested Fields and Dynamic Arrays with FieldArray

In this episode, we tackle nested fields and dynamic form arrays using Formik’s FieldArray component. You’ll learn how to dynamically add, remove, and manage repeating groups of fields while preserving validation and state consistency. This video is essential for building complex, scalable forms such as multi-step forms, nested data structures, or any dynamic form scenario in modern React applications.
