react-armory-reversible-list

This package is designed to demonstrate why you need key props on React Elements in arrays. It exports a ReversibleList component that expects a single array as a child, and renders these children along with a "Reverse" button -- which will only work if the child array has keys.

Exports

• <ReversibleList children={array}>
