Promiser
Make your promises prettier with this simple wrapper, that can help you write promises without using a callback!
Usage
function foo() { const promiser = new Promiser(); setTimeout(() => { let lucky = Math.random(); if (lucky > 0.8) promiser.resolve("Oh yes! You're very lucky!"); else promiser.reject("I suggest you to try again :( ... next year"); }, 1500); return promiser.promise; }
You can also check if a Promiser
instance has already been solved by calling promiser.isSolved
getter which will return true
if promiser
has been solved and false if not.
A single instance of Promiser
can be used only once, so once you have solved your promise, that instance can't be reused for resolving/rejecting any other value!
