3. useCallback을 사용해야할 때

But in some cases you need to maintain a single function instance between renderings:

1. A functional component wrapped inside React.memo() accepts a function object prop
2. When the function object is a dependency to other hooks, e.g. useEffect(..., [callback])
3. When the function has some internal state, e.g. when the function is debounced or throttled

Don't forget that useCallback() hook is called every time MyComponent renders. Even useCallback() returning the same function object, still, the inline function is re-created on every re-rendering (useCallback() just skips it).

함수가 다루는 것이 간단하다면 쓸필요가 없다.

4. LocalStroage vs LocalForage

LocalStorage API is synchronous and accepts simple key value strings.

LocalForage leverage this simple interface with Promises to get/set values and gives the ability to store more than converted strings as data.

If you are familiar with the logic of LocalStorage and you are experimenting with something new I suggest you give it a try.
