Custom Form Validation in React JS without any package.

Assalamo Alaikum,

This video is about Custom form validation in React JS.

One Initial Form Object,
Two states ( formData, errorMessage),
Two handler functions,
One useEffect hook, and,
a custom validator function.

Here I have only used an if-else condition for validation.

You must use Regular Expression/ RegEx in order to make hard validations.

Thank you.
