On what to implement the interface of the difficult form?

Question

JavaScript

You need to create a complex form to fill out with validation in your crm. Form with different branches, new questions should appear depending on the answer of the previous ones. The fields are different.
They suggested that React is well suited for this, with which I did not work, only with javascript. Tell me, for sure there are ready-made and convenient libraries for this? Thank you.

Answer 1

Know native js - use that and regex to validate values.
