Ideas for defining properties on Javascript "classes"

gistfile1.js

// Method 1:
MyClass = Class({
	extends : "AnotherClass",
	
	mixins : ["Event"],
	
	construct : function () {
		console.log("constructor message");
	},
	
	static : {
		prop : 5
	},
	
	private : {
		
	},
	
	protected : {
		
	},
	
	public : {
		testFunc : function () {
			// do something ...
		}
	}
});

//Method 2:
MyClass = Class({
	extends : "AnotherClass",
	
	mixins : ["Event"],
	
	construct : function () {
		console.log("constructor message");
	},
	
	contents : {
		"prop" : {
			value : 5,
			final : "true|false",
			visibility : "public|protected|private",
			static : "true|false"
		},
		
		"testFunc" : {
			value : function () {
				// do something...
			},
			final : "true|false",
			visibility : "public|protected|private",
			static : "true|false"
		}
	}
});
