-Most props on a JSX element are passed on to the component, however, there are two special props (`ref` and `key`) which are used by React, and are thus not forwarded to the component.
+Most props on a JSX element are passed on to the component. In earlier versions of React, `key` and `ref` were two special props used internally by React that were not forwarded to components.
 
-For instance, you can't read `props.key` from a component. If you need to access the same value within the child component, you should pass it as a different prop (ex: `<ListItemWrapper key={result.id} id={result.id} />` and read `props.id`). While this may seem redundant, it's important to separate app logic from hints to React.
