数组

// 基础用法:type[]
let arr:number[] = [1,2,3]

// 泛型用法：Arrary<type>
let arr1:Array<boolean> = [true,true]

// interface用法: interface[]
interface x {
  name: string
  age?: number
}
let arr2:x[] = [{name:'lq'}, {name:'lq1', age: 10}]

// 二维数组：套娃方式，叠在在后面
let arr3:number[][] = [[1],[2]]
let arr4:Array<Array<boolean>> = [[true],[true]]

// 大杂烩使用any或者元组格式
let arr5:any[] = [1,'2',{},true]
let arr6:[number,string,object,boolean] = [1,'2',{},true]

// args是数组格式
function fn(...args:string[]) {
  console.log(arguments,'是类数组格式,{"0":"1","1":"2",}');
  // IArguments是类数组
  let arg:IArguments = arguments
}
fn('1','2','3')
