I come to react (as well as react-native) with typescript, of course, I'm a beginner, so soon my company assigns me to support a javascript project, and I have javascript questions

In typescript, if we want to use props, I think the best, also cool way to do that is using Interface, it also let me have IntelliSense code in vs code

export interface FooI {
  some: string;
  propsA: string;
  here: number;
}

And use that in component:

export default function Bar(props: FooI) {
  const {some, propsA, here} = props;
}

And we also can inherit react component( in this case is react-native), so if I want the component will be a button, so I add

export interface FooI extends ButtonProps {
  some: string;
  propsA: string;
  here: number;
}

As I know we don't have that in javascript, so what is similar to the interface in javascript so I can create a custom component like above and vs code will recognize that and show an auto-complete pop-up?
