Regarding javascript inheritance class.

Question

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()

Answer 1

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

NimaPoshtiban I want to add new method to parents class that I want to use later , how to add new method to the parent class without writing code inside parent class ? Please help me

NimaPoshtiban thank you so much , you helped me lot

Answer 4

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
