[Dart/TypeScript] Similarities and Differences. Static typing with type inference, single inheritance, abstract classes, Mixin, asynchronous
Both Dart and TypeScript are statically typed languages (types are determined at compile-time), but type annotations are optional and strong type inference works: abstract classes in Dart provide a means of enforcing concrete implementations in subclasses, while interfaces in TypeScript provide a means of enforcing a specific structure in classes. TypeScript interfaces provide a means of enforcing a specific structure on a class.
