1.布尔值

let isDone:boolean = false

2.数字（支持二，八，十，十六进制）

let width:number = 20

3.字符串

let name:string = "Bob";
模板字符串：
let sentence:string = `hello,my name is ${name}`;

4.数组

let list:number[] = [1,2,3,4];
let list:Array<number> = [1,2,3,4]

5.元祖 Tuple:已知元素数量和类型的数组，各类型可不相同

let x:[string,number];
x = ["Bob",18]

6.枚举Enum
