React. Don't warn about missing child's key prop in array of childs.

I study this tutorial. https://reactjs.org/tutorial/tutorial.html#showing-the-moves. It says, that then I render array of childs without key prop, there should be warning about it. WebStorm does not issue any warning. Why?

This is just a warning thrown by React in runtime. we don't have a set of React inspections to check this kind of things; if you miss them, please feel free to file a feature request to youtrack, https://youtrack.jetbrains.com/issues/WEB
