Simplest Formik Tutorial / React js Formik

Formik is the world's most popular open source form library for React and React Native.

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
