[React 19] Need suggestion on upgrade.

[lakshman0369]

Summary

We are upgrading the react in our project and we see in the documentation the support for the defaultprops and proptypes is removed.

We are using the jsx and migrating to typescript is not possible at the moment as our project is fairly big. Any suggestion on how to do defaultprop and proptype check.

You can use defaultprops and proptypes on your component or you can try JSDoc comments

Here is something I came up with, along with some help form my AI agent. This is the short version - if you want the long one, let me know:

• Use ES6 default parameters for setting default values in your functional components.
• Continue using prop-types for runtime validation of props to prevent passing incorrect data types.
• Plan for a gradual migration to TypeScript, as that will ultimately offer the strongest and most scalable type safety long-term.
