我可以在打字稿上做到这一点吗？

doSomething():void;
}
export class MyBaseClass {
myBaseClassHasProperty:string;
constructor(){
this.myBaseClassHasProperty = 'some value';
}
myBaseClassHasMethods():void{
console.log(this.myBaseClassHasProperty);
}
}
export class MyClass extends MyBaseClass implements IMyInterface {
constructor(){
super();
}
doSomething():void{
this.myBaseClassHasMethods();
}
}

Yes you can do that. The code you posted will work fine.
是的，你可以这样做。您发布的代码将正常工作。
However I suspect in your actual codeyou have it split across multiple files and MyBaseClassis not executedbefore the code for MyClass.
但是，我怀疑在您的实际代码中，您将其拆分为多个文件，MyBaseClass并且不会在MyClass.
