I want to do this:
class Parent {
static myMethod1(msg) {
// myMethod2 is undefined
this.constructor.myMethod2(msg);
}
}
class Child extends Parent {
static myMethod2(msg) {
console.log('static', msg);
}
}
Child.myMethod1(1);
But it doesn't work. Is this possible some other way? I don't want to hard code Child.myMethod2 in Parent which I know would work since I want random child classes to be able to define/override the static method but call that method from the parent without prior knowledge of which class is the child.
myMethod2 is undefined because the code is wrong. this is class constructor in static methods, and this.constructor is the constructor of a constructor, i.e. Function. It should be:
class Parent {
static myMethod1(msg) {
this.myMethod2(msg);
}
}
This is antipattern, because Parent doesn't have myMethod2, and Parent.myMethod1() will result in error. It should either contain no-op myMethod2, or be labeled as abstract class to never be accessed directly.
