In plain English

Formik is a TypeScript library for building forms in React and React Native applications. Forms in web apps involve a lot of repetitive logic, tracking what the user has typed, validating inputs, handling submission, and showing error messages, and Formik is designed to handle all of that without the developer having to wire it up manually each time. It supports both hooks and higher-order components, which are two different patterns for sharing logic between React components. The README in this repository only contains a file path rather than actual documentation, so a complete explanation of its features is not possible from the provided data alone.
