Descrizione

The this keyword on static methods refers the class instance (the constructor). This can be confusing.

Fail

class A {
    static foo() {
        doSomething()
    }

    static bar() {
        this.foo()   //ERROR: Unexpected 'this'.
    }
}

class B extends A {
    static foo() {
        super.foo()  //ERROR: Unexpected 'super'.
    }
}

Pass

class A {
    static foo() {
        doSomething()
    }

    static bar() {
        A.foo()
    }
}

class B extends A {
    static foo() {
        A.foo()
    }
}
