    this.variable = variable;
  }
 
  method() {
    return this.variable;
  }
}
 
// create clone
const CloneA = createCloneClass(A);
 
// modify original
A.prototype.method = () => 'override original';
 
const clone = new CloneA('clone');
const original = new A('original');
 
clone.method(); // returns 'clone';
original.method(); // returns 'override original';
