a-defer

Create a deferred promise

Don't use this unless you know what you're doing. Prefer the Promise constructor.

Install

$ npm install a-defer

Usage

import aDefer from 'a-defer';

function delay(milliseconds) {
  const deferred = aDefer();
  setTimeout(deferred.resolve, milliseconds, '🦄');
  return deferred.promise;
  // or
  // return deferred;
}

console.log(await delay(100));
//=> '🦄'

The above is just an example. Use delay if you need to delay a promise.

API
