TypeScript mixins: Examples and use cases

TypeScript mixins provide a solution to the limitation of single inheritance by allowing multiple class inheritance, which is useful for building complex applications. Mixins are special classes that contain methods usable by other classes, promoting code reusability and overcoming limitations associated with multiple inheritance. By utilizing TypeScript features like interface class extension and declaration merging, developers can create mixins that allow a class to inherit properties and methods from multiple classes, as demonstrated through a practical example involving a Block class that extends Moulder and Stacker classes. This method relies less on the compiler and more on the codebase to maintain sync between runtime and type-system, making it an optimized approach. Although there are other ways to implement mixins, this approach is highlighted as a highly effective way to manage complex architectures in TypeScript.
