# 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 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 ``` ## Related - [More…](https://github.com/sindresorhus/promise-fun) ## License MIT © [Sindre Sorhus](https://sindresorhus.com)
