Dynamic Form Json

dynamic-form-json is a tiny library to generate a Form in React automatically based on certain array of object that passed as a props. This library use regular css created from scratch, so user can customize it in the future. On top of it, i use Formik and Yup for form's skeleton and validations. Credit goes to vijayranghar for the inspiration how to create dynamic validation on Yup from this link.
