## README

# p-is-promise

> Check if something is a promise

Why not [`is-promise`](https://github.com/then/is-promise)? That module [checks for a thenable](https://github.com/then/is-promise/issues/6), not an ES2015 promise. This one is stricter.

You most likely don't need this. Just pass your value to `Promise.resolve()` and let it handle it.

Can be useful if you need to create a fast path for a synchronous operation.

## Install

```
$ npm install p-is-promise
```

## Usage

```js
import isPromise from 'p-is-promise';
import Bluebird from 'bluebird';

isPromise(Promise.resolve('🦄'));
//=> true

isPromise(Bluebird.resolve('🦄'));
//=> true

isPromise('🦄');
//=> false
```
