# p-is-promise [](https://travis-ci.org/sindresorhus/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 --save p-is-promise
```
## Usage
```js
const pIsPromise = require('p-is-promise');
const Bluebird = require('bluebird');
pIsPromise(Promise.resolve('🦄'));
//=> true
pIsPromise(Bluebird.resolve('🦄'));
//=> true
pIsPromise('🦄');
//=> false
```
