final def useCallback[A](callback: A)(implicit isCallbackArg: UseCallbackArg[A]): HookResult[Reusable[A]]
Returns a memoized callback.
Returns a memoized callback.
Pass an inline callback and dependencies. useCallback will return a memoized version of the callback that only changes if one of the dependencies has changed. This is useful when passing callbacks to optimized child components that rely on reference equality to prevent unnecessary renders.

final def useContext[A](ctx: Context[A]): HookResult[A]
Accepts a context object and returns the current context value for that context.
Accepts a context object and returns the current context value for that context. The current context value is determined by the value prop of the nearest <MyContext.Provider> above the calling component in the tree.
When the nearest <MyContext.Provider> above the component updates, this Hook will trigger a rerender with the latest context value passed to that MyContext provider. Even if an ancestor uses React.memo or shouldComponentUpdate, a rerender will still happen starting at the component itself using useContext.
A component calling useContext will always re-render when the context value changes. If re-rendering the component is expensive, you can optimize it by using memoization.
useContext(MyContext) only lets you read the context and subscribe to its changes. You still need a <MyContext.Provider> above in the tree to provide the value for this context.

final def useEffect[A](effect: A)(implicit isEffectArg: UseEffectArg[A]): HookResult[Unit]
The callback passed to useEffect will run after the render is committed to the screen.
The callback passed to useEffect will run after the render is committed to the screen. Think of effects as an escape hatch from React’s purely functional world into the imperative world.
By default, effects run after every completed render. If you'd only like to execute the effect when your component is mounted, then use useEffectOnMount. If you'd only like to execute the effect when certain values have changed, then use useEffectWithDeps.

final def useMemo[D, A](deps: => D)(create: (D) => A)(implicit arg0: Reusability[D]): HookResult[Reusable[A]]
Returns a memoized value.
Returns a memoized value.
Pass a “create” function and any dependencies. useMemo will only recompute the memoized value when one of the dependencies has changed. This optimization helps to avoid expensive calculations on every render.
Remember that the function passed to useMemo runs during rendering. Don’t do anything there that you wouldn’t normally do while rendering. For example, side effects belong in useEffect, not useMemo.

final def useReducer[S, A](reducer: (S, A) => S, initialState: => S): HookResult[UseReducer[S, A]]
An alternative to useState.
An alternative to useState. Accepts a reducer of type (state, action) => newState, and returns the current state paired with a dispatch method. (If you’re familiar with Redux, you already know how this works.)
useReducer is usually preferable to useState when you have complex state logic that involves multiple sub-values or when the next state depends on the previous one. useReducer also lets you optimize performance for components that trigger deep updates because you can pass dispatch down instead of callbacks.

Allows components to avoid undesirable loading states by waiting for content to load before transitioning to the next screen. It also allows components to defer slower, data fetching updates until subsequent renders so that more crucial updates can be rendered immediately.
**If some state update causes a component to suspend, that state update should be wrapped in a transition.**
