Summary

In this chapter, we created a reusable checklist component and used many useful patterns along the way.

We started by learning how to implement generic props, which allow a component to be used with varying data types but still be strongly typed. We used this to allow varying data to be passed into the checklist component without sacrificing type safety.

We learned how to allow consumers of a component to spread props onto an internal element. A common use case is spreading props onto the internal container element to allow the consumer to size it, which is what we did with the checklist component.

The render prop pattern is one of the most useful patterns when developing reusable components. We learned that it allows the consumer to take responsibility for rendering parts of the component. We used this pattern to override the rendering of list items in our checklist component.

Custom hooks isolate logic and are useful for sharing logic across components and keeping...
