| |
| > 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 |
| const pIsPromise = require('p-is-promise'); |
| const Bluebird = require('bluebird'); |
| |
| pIsPromise(Promise.resolve('🦄')); |
| //=> true |
| |
| pIsPromise(Bluebird.resolve('🦄')); |
| //=> true |
| |
| pIsPromise('🦄'); |
| //=> false |
| ``` |
