JavaScript React Basics (retired) Thinking in Components Properties Review

How do you type check with a PropType?

Specifically type checking for strings

I haven't seen the course you're going through. There are different strategies but you don't necessarily need to with React just straight out of the box. One strategy is to: import PropTypes from 'prop-types'

assuming PropTypes is in your project. then you could say

SomeReactComponent.propTypes = { name: PropTypes.string }
