Well, as of October 2023 Formik is deprecated because it is no longer maintained, you can find the link to the GitHub comment by the maintainers where it is suggested to use React Hook Form

Link for reference

Jimivi I don't think so
because formik is the most popular form validation in the latest web apps.

React hook form all the way baby!

[ANKUR SHARMA]

There is very simple way to validate emails with Yup like you only write Yup.email().required (). Now, you can't write the complex regex for the validation of the emails

[ZeeshanMustfai]

We can also write your own regex for complex email validation. for example
Yup.string()
.required("Email is required")
.matches(
/^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+.[a-zA-Z]{2,4}$/,
"Invalid email format"
)

[ANKUR SHARMA]

Yes
