clean-promise

A minimal and clean implement of JavaScript ES6 Promise, which passes all standard test cases.

Features

• multiple ES6 features are applied: const/let, Class, Symbol, => etc
• clean, explict and fast
• both available on back-end and front-end

Installation

> npm install clean-promise --save

Usage

You can use it like this in your own code:

const Promise = require('clean-promise');

Promise.all([Promise.resolve(1), 2, 3]).return(4444)
    .tap(v => {
        console.log('1 ' + v);
    }).tap(v => {
        console.log('2 ' + v);
    }).return(3).tap(v => {
        console.log('2 ' + v);
    });
