// typescript基础数据类型
// Boolean, Number, String, Array, Enum（枚举）, Any, void
定义布尔类型
var isBoon:boolean = false;
定义数字类型
var num:number = 10;
定义字符串类型
var str:string = 'adsf';
定义数组类型
var list1:number[] = [1, 2, 3];
var list2:Array<number> = [4, 5, 6];
定义枚举
// 定义角标
enum Color {Red = 1, Green, Blue};
var colorName:string = Color[2]; // Green
// 所有的项，都定义角标
enum Color {Red = 1, Green = 15, Blue = 20};
var colorName:string = Color[15]; // Green
返回角标
enum Color {Red = 1, Green = 15, Blue = 20};
var c:Color = Color.Green; // 15
定义任意类型
var notSure:any = "123";
notSure = 123;
notSure = false;
var list:any[] = [1, '2', true];
var list:Array<any> = [1, '2', true];
