in-promise is a minimal Promises/A+ implementation for browsers.

~700 bytes (gzip).

# API

It is really _minimal_, and only provides a ES6 style Promise constructor plus a Promises/A+ compatible `Promise#then` method:

```js

var p1 = new Promise(function (res, rej) {

  setTimeout(function () {

    res('Hello Promise')

  }, 100)

})

var p2 = p1.then(function (value) {

  console.log(value) // Hello Promise

})

```

This is no `Promise#catch` or `Promise.all` or `Promise.race` or ...

Just `Promise#then`.

For a polyfill for ES6 Promise, check the [es6 branch].
