querablep

Allows you to ask your promise few questions:

• is it done? (finished, whatever is the result)
• is it resolved? (success)
• is it rejected? (failure)

Usage

.. code:: javascript

const querablep = require('querablep')

// Business code const peoplePromise = querablep(getPeopleInDatabasePromise());

peoplePromise.isFulfilled(); // false peoplePromise.isRejected(); // false peoplePromise.isResoleved(); // false

peoplePromise

.catch((e) => {
  peoplePromise.isFulfilled(); // true
  peoplePromise.isRejected();  // true
  peoplePromise.isResoleved(); // false
})

.then((people) => {
  peoplePromise.isFulfilled(); // true
  peoplePromise.isRejected();  // false
  peoplePromise.isResoleved(); // true
});
