Special Props Warning

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.

For instance, attempting to access this.props.key from a component (i.e., the render function or propTypes) is not defined. 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} />). While this may seem redundant, it’s important to separate app logic from reconciling hints.
