Why Props interface in React with TypeScript but not in React Native?

I’m new to the field. Just finished React for Beginners and started React Native.

One thing that bugs me is that in the React course whenever we wanted to pass a prop to a custom component we created a Props interface in that component but in React Native we simply don’t.

Is it optional?

Does it have something to do with Typescript or what?

Excuseme if the answer it is too simple and I’m missing something obvious.

Thanks
