Thenable

Thenable object (an object with then method)

thenable/is

Confirms if given object is a thenable

```javascript const isThenable = require("type/thenable/is");

isThenable(Promise.resolve()); // true isThenable({ then: () => {} }); // true isThenable({}); // false ```

thenable/ensure

If given argument is a thenable object, it is returned back. Otherwise TypeError is thrown.

```javascript const ensureThenable = require("type/thenable/ensure");

const promise = Promise.resolve(); ensureThenable(promise); // promise ensureThenable({}); // Thrown TypeError: [object Object] is not a thenable object ```
