typescript 定义类型

type infoType = string;
let name: infoType = "全易";
let location: infoType = "北京";
// let age: infoType = 18; // 报错 infoType = string｜number 就不报错了
let job: infoType = "开发";
let love: infoType = "吃喝玩乐";type Type1 = {name: stringlocation: stringage: numberslogan?: stringjob: string
}
type Type2 = {love: stringmoney?: number
}
// 交叉Type1和Type2的规则
type Type3 = Type1 & Type2;
let obj: Type3 = {name: "全易",location: "北京",age: 18,job: "开发",love: "吃喝玩乐"
}
function fn(params: Type3) {console.log(params);
}
fn(obj)
