    method0: function() { 
      console.log('Hello, from method one.') 
    }, 
       method1() { 
      console.log('Hello, from method one.') 
    } 
  }; 
  obj.method0(); 
  obj.method1(); 
 
  obj.method0 = () => console.log('Override of method 0.'); 
  obj.method1 = () => console.log('Override of method 1.'); 
  obj.method0(); 
  obj.method1(); 
}
