I have found many examples of traits and mixins in typescript, but I miss the way to access public trait method inside the class using the trait Is there a way to have compilator valid trait complete implementation?

class A {
  methA() {}
}

class B {
  methB(){}
}

class C extends B { // and things like "use A"
  methC() {
    this.methA()+this.methB()
  }
}
car c = new C
c.methA()+c.methB()==c.methC()

I tried with an ugly Object.assign(this, new A) but TSC doesn't detect it.

This is called aspect-oriented programming. JavaScript (and TypeScript) do not support AOP. – Parzh from Ukraine Sep 05 '22 at 16:53
There's no `Object.this(…)` in standard library. – Parzh from Ukraine Sep 05 '22 at 16:55
Typescript has no traits at all. What you're using is inheritance. – Alejandro Sep 05 '22 at 16:55
