描述

The useDeferred() hook creates and stores in a state slot (via useState(..)) an object, commonly called a deferred, which is a promise and also its resolve(..) / reject(..) capabilities.

function foo() {
   var { pr, resolve, reject } = useDeferred();
}

Unclear if there's any pattern that would benefit from passing a value to useDeferred(..). Need to further consider.

研究方向
First, examine the existing `useState` and other hooks in TNG Hooks to understand the pattern. Then, determine if `useDeferred` should accept a value argument by considering use cases where an initial value might be needed. Look at discussion in related issues or similar implementations like React's `useDeferredValue`. The implementation likely resides in the `src/hooks` directory.
