+Now Overmind also sees that this component is interested in the id and title of every item. Meaning that if any id or title changes this component would render again. This is perfectly okay for the most part, but if each child renders a complex UI in itself it is a good idea to separate it into its own component. That means each item from the array will be passed to a component as a prop.
