 `union()` accepts [set-like](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set#set-like_objects) objects as the `other` parameter. It requires {{jsxref("this")}} to be an actual {{jsxref("Set")}} instance, because it directly retrieves the underlying data stored in `this` without invoking any user code. Then, it iterates over `other` by calling its `keys()` method, and constructs a new set with all elements in `this`, followed by all elements in `other` that are not present in `this`.
