Let's face it, forms are really verbose in React. To make matters worse, most form helpers do wayyyy too much magic and often have a significant performance cost associated with them. Formik is a small library that helps you with the 3 most annoying parts:
- Getting values in and out of form state
 - Validation and error messages
 - Handling form submission
 
By colocating all of the above in one place, Formik will keep things organized--making testing, refactoring, and reasoning about your forms a breeze.
You can play with Formik in your web browser with these live online playgrounds.
