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.
