-### isPromise

 Returns `true` if an object looks like a [`Promise`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise), `false` otherwise.
 
 Check if the object is not `null`, its `typeof` matches either `object` or `function` and if it has a `.then` property, which is also a `function`.
 
 ```js
-const isPromise = obj =>
+const isPromiseLike = obj =>
   obj !== null && (typeof obj === 'object' || typeof obj === 'function') && typeof obj.then === 'function';
 ```
 
 ```js
-isPromise({then:function () {return ''}}); // true
-isPromise(null); // false
-isPromise({}); // false
+isPromiseLike({then:function () {return ''}}); // true
+isPromiseLike(null); // false
+isPromiseLike({}); // false
 ```
