//1.使用Array对象创建数组

//数组元素是字符型

var city = new Array("北京","上海","深圳");

//数组元素是数值型

var score = new Array(80,100,96);

//数组元素是混合型

var mix = new Array("abc",123,false,true,undefined);

console.log(mix);

console.log(city);

console.log(score);

//创建空数组

var arr1 =new Array();

var arr2 =new Array;

//使用[]创建数组

var weather = ["wind","fine"];

var empty =[];

var mood = ["sad","","","happy"];
