Regarding javascript inheritance class.

I have a class "Commands" I want to create the method inside class "Commands" but I don't want to manually write method on Commands class , I want to import or inheritance like something to create method "run()" in class "Commands" . Later I want to access this by writing : var cmd = new Command ().run() R♡$€☆ I Am Rochie Vishnu Saini 💕₽ΔŘI💕[Inactive] Reetika Ria Sick!!Nikhat Shah (Dm Closed)

Ok i understand this is what you should do: class Parent { run() { return "something to return"; } } Parent.prototype.talk = function() { return "something to say"; } class Command extends Parent { constructor() { super(); } } var cmd = new Command().talk(); // how to do it // write : ParentClass.prototype.methodName = function(){...} // you should use prototypes

this is how to do it: class Parent { run() { return "something to return" } } class Command extends Parent { constructor() { super(); } } var cmd = new Command().run(); // Desc: // We define run function inside the parent class // Then Command class should inherit from parent class // in constructor we should call super() to inherit all parent class props // side note: other OOP languages might have some different approaches // There is no actual class in javascript , javascript uses prototypes concept
