数字型
const numberArr : number[] = [1,2,3,4,5,6,7,8,9]

字符串型
const stringArr : string[] = ['a','b','c','d','e']

const  : UndefinedArr : Undefined[] = [Undefined,Undefined,Undefined]

const arr : (nuber | string)[] = [2,"史迪奇",3]

const sdq: {name:string,age:number}[] = [
    {name:"史迪奇",age:2001},
    {name:"史迪仔",age:2001}
]

type sdz ={name:string,age:number}
class Madam {
    name:string;
    age:number;
}
const sdq: Madam[] = [
    {name:"史迪奇",age:2001},
    {name:"史迪仔",age:2001}
]

const sdq:[string,string,number] = ['史迪奇','雄性',626]

const sdq:[string,string,number] []= [
    ['史迪奇','雄性',626],
    ['鲁本','雄性',625],
