Hey everyone
I’m doing Mosh’s **React 18 for Beginners** course. In _Building Components, Lesson 11_. When passing more complex children as props to a React component (comprising of other HTML elements), Mosh sets the `children` prop to the type `ReactNode`.
My question is, how and where would I find that information? If for example there are more types.
Cheers

Here is some documentation on react props. This what ya are looking for?

Thanks for the reply, I probably should have explained it better.
It’s a TypeScript thing, when defining the values of function arguments; one argument that will come from props, is the `children` object. In this example is more than simply some text, it could contain HTML. The TypeScript type is set to `ReactNode`
`interface Props { children: ReactNode; onClose: () => void; }`
Which is an import from react: `import { ReactNode } from "react";`
How do I find out what the `children` object should be?
Cheers

It’s a tricky topic i’ve tried defining props for a form submission and pass the data to a usestate ended up having to pass a html fotm element instead of my prop and that made it work.
I could use a refresher tbh from the course.
