Deferred ​

deferred is a variation of promise. It is different from promise in that it also adds resolve and reject methods, which make it easy to control the flow of the promise externally.

Typically, you don't need to use it, as deferred is defined by default in the constructor to control the entire overlays flow.

const deferred = createDeferred<string>()

deferred.then((value) => {
  // value: yes!
})

deferred.resolve('yes!')

await deferred // yes!
