The NOT (!) operator for promises

Install promise-not using npm:

npm install --save promise-not

var not = require('promise-not');

not(Promise.resolve(false))
  .then(function (val) {
    // val === true
  });

Returns: Promise, which resolves to the invers of what val resolves to.

• promise-or
• promise-and
