use-what-changed VS formik

https://github.com/simbathesailor/use-what-changed - what's nice about it is it gives detailed information about why a component renders, upon each render, along with diffs of what actually changed. It works for hooks - I haven't found a really good trick for debugging context renders yet though.

Nowadays, I tend to opt for the useWhatChanged hook. Ergonomically it's a little easier, and its plug-and-play use makes it very attractive.

Additionally, there are more npm packages such as Formik and zod that come equipped with a range of features that can enhance the form validation process.

7. Formik and Yup

Forms are often tricky to get right with React. While there are great libraries like formik or React Final Form to do the heavy lefting for us, handling file upload still isn't always straightforward.

Formik is a well known React library that allows to create forms, manage, and validate their state. It comes with built-in support for Yup, a schema builder for value parsing and validation.

Formik is a small group of React components and hooks for building forms in React and React Native. Formik helps with the three most annoying parts: Getting values in and out of form state. Validation and error messages. Handling form submission. npm i formik

Formik

In the first part of this tutorial, we took a look at how to build React forms with custom HTML elements and form state and logic provided by Formik. In the second part, we switched to Formik components and build form with them. In this final part we will make another change, a small step back.
