Inheritance PlayCanvas

I want to make an base script/class that can be called from other script like this

base class person{
eat(){
console.log("eat")
}
}


sub class bob extends person{}
sub class rolland extends person{}


eaterclass(){
initialize(){
this.entity.person.eat();
}
}

on this.entity would be an bob script

how can I do this?
