# Formik 2.0

Formik takes care of the repetitive and annoying stuff--keeping track of values/errors/visited fields, orchestrating validation, and handling submission--so you don't have to. This means you spend less time wiring up state and change handlers and more time focusing on your business logic.

Formik has some major performance issues due to it's use of the React Context. Any modification of the Formik context will cause the entire form to rerender. Imagine a text field that validates on change using Yup, thats an entire form render on every key stroke. If you have controlled components, forget about, it's a dog.
