Implement usePrevious

Description

Implement a usePrevious hook and use it in a comparison component. It should return undefined on the first render and the prior committed value thereafter.

Requirements

usePrevious returns undefined for the first committed render.
After rerendering, usePrevious returns the value from the preceding committed render.
Updating the stored previous value does not trigger an additional component render.
The exported hook preserves the TypeScript type of primitive, object, and undefined values.

Value update

Input

Render with A, then render with B

Expected output

The hook returns A after the second render

Constraints

Do not cause an additional render
Preserve the generic value type
Return undefined initially

Hints

Hint 1

Choose storage whose updates persist across renders without scheduling another render.

Hint 2

Read the stored value during render, but update the storage only after the current render commits.

Hint 3

Parameterize both the hook input and its nullable initial result so TypeScript preserves the caller's value type.
