Cant call static owerriden methods, if i write Animal.run() this is code not use Cat.run owerriden method. i need write this.constructor.run() but it get compilation error.

class Animal {

    static run (){
        alert('Animal run')
    }

    run(){
        this.constructor.run() // compile error
        // if i write Animal.run() this code not use Cat.run owerriden method
    }

}


class Cat extends Animal {

    static run (){
        super.run()
        alert('Cat jump')
    }

}

let cat = new Cat()
cat.run()

solution

add keyword static for access to current static props, static will be alias for this.constructor in self methods, and alias for this in static methods

and code will be:

class Animal {

    static run (){
        alert('Animal run')
    }

    run(){
        static.run() // compile to this.constructor.run()
    }

}


class Cat extends Animal {

    static run (){
        super.run()
        alert('Cat jump')
    }

}

let cat = new Cat()
cat.run() // alert('Animal run') alert('Cat jump')

dangers

Static keyword to be used in the following standards and ES have different semantics
