After creating our custom Hooks, we can now start using them throughout our blog application. Using custom Hooks is quite straightforward as they are similar to community Hooks. Just like all other Hooks, custom Hooks are simply JavaScript functions.

We created the following Hooks:

• useTheme
• useDispatch
• usePostsState
• useUserState
• useDebouncedUndo
• useAPILogin
• useAPIRegister
• useAPICreatePost
• useAPIThemes
  

In this section, we are going to refactor our app to use all of our custom Hooks.
