# Mixed

typedef

Helper type that creates constructor types from a base class and a mixin interface.

```typescript
interface MyMixinInterface {
	mixinMethod(): void;
}

function MyMixin<Base extends Constructor>( base: Base ): Mixed<Base, MyMixinInterface> {
	// ...
}

class BaseClass {
	baseMethod(): void {
		// ...
	}
}

const MixedClass = MyMixin( BaseClass );

// Contains both `mixinMethod()` and `baseMethod()`.
const myObject = new MixedClass();
myObject.mixinMethod();
myObject.baseMethod();
```
