Which is more cumbersome?

    //Objective-C
    
    #import <Foundation/Foundation.h>
    
    @interface Order : NSObject {
    	NSString *id;
    	Customer *customer;
    	NSDate *timestamp;
    	NSString *productId;
    }
    
    @property (nonatomic, retain) NSString *id;
    @property (nonatomic, retain) Customer *customer;
    @property (nonatomic, retain) NSDate *timestamp;
    @property (nonatomic, retain) NSString *productId;
    
    @end
    
    #import "Order.h"
    
    @implementation Article
    
    @synthesize id;
    @synthesize customer;
    @synthesize timestamp;
    @synthesize productId;
    
    - (void)dealloc
    {
    	[self setId:nil];
    	[self setCustomer:nil];
    	[self setTimestamp:nil];
    	[self setProductId:nil];
    	[super dealloc];
    }
    
    //Javascript
    
    Order = Proto.clone().newSlots("id", "customer", "timestamp", "productId");
