		// 数组 
		var arr = new Array();//  定义数组  或者  var arr = [] 
		console.log("数组初始化:"+arr);
		arr.push("arr1","arr2","arr3","arr4");  // 数组加数据
		console.log("arr:"+arr);   //  结果： arr:arr1,arr2,arr3,arr4
		console.log(" ");
		
		// Json
		var json = {};     // 定义 JSon
		console.log("Json初始化: "+json);  // 结果:Json初始化:[object Object]
		json["name"] = "Ben";
		json["age"] = 12;
		console.log("Json取值: "+json.name +":"+json.age);   // 结果:Json取值: Ben:12
		
		// 定义对象
		var object = new Object();  
		console.log("Object初始化: "+object);  // 结果： Object初始化: [object Object]
		object.name = "Ben";
		object.age = 12;
		console.log("对象Object: "+object.name +"："+object.age);  // 结果:  对象Object: Ben：12
		
		// 定义Json 数组
		var jsonArr = [];
		jsonArr.push(json);
		console.log("Json数组jsonArr: "+jsonArr[0].name );  // 结果：Json数组jsonArr: Ben
		
		// 定义Json 对象
		var objArr = [];
		objArr.push(object);
		console.log("Json对象objArr: "+objArr[0].name);  // 结果： Json对象objArr: Ben
		
		console.log("Json转String  " + JSON.stringify(object));  // 结果：Json转String  {"name":"Ben","age":12}
		var str = JSON.stringify(object);
		console.log("String转Json " + JSON.parse(str));  // 结果：String转Json [object Object]
