A beginner-friendly introduction to Formik, a popular React form management library. Covers the two main APIs (useFormik hook and Formik component), built-in Form and Field components, input states (touched, dirty, isSubmitting), dynamic field arrays with FieldArray, and form validation using both custom functions and the Yup schema library. Includes working StackBlitz examples for each concept, from basic text inputs to checkboxes and password confirmation fields.
