Description

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.

Contributor guide

Research direction
Investigate common patterns for deferred objects in JavaScript, look into existing implementations (e.g., in React's experimental hooks or libraries). Consider whether a value parameter would be useful by analyzing scenarios where the deferred promise might need initial data.
