It depends how you construct Dog and Cat. With Javascripts dynamic prototype chain, you could never know for sure.

    type Mutt = Dog & Cat

    const imposter: Mutt = { bark: () => console.log("woof"), meow: () => console.log("meow"), }

    You're both misunderstanding parent's point as well as the original point. Nobody ever claimed your link wouldn't compile.

      I see what you mean, thanks

      Well imo GP is fundamentally misunderstanding TypeScript. It's explicitly a structural language not a nominal one. It goes against the entire design philosophy of TS
