一、基本类型

num = 1，
str = '字符串',
falg = true

2、数组

arr: any = [];

1.单一数组

 arr: number[] = [];//或arr: Array<number> = [];

2.数组对象

interface Comma {[k: string]: boolean;
}
//或
interface Comma {index: string | number;name: string;[propName: string]: any;
}type DataList = Comma[];commaIndex: DataList = [];

3.对象

interface Comma {[k: string]: any;
}subject: Comma = {};
