Typescript中interface与type的相同点与不同点的详细说明

interface User {
  name: string
  age: number
}

interface SetUser {
  (name: string, age: number): void;
}

type User = {
  name: string
  age: number
};

type SetUser = (name: string, age: number)=> void;

interface Name { 
  name: string; 
}
interface User extends Name { 
  age: number; 
}

type Name = { 
  name: string; 
}
type User = Name & { age: number  };

type Name = { 
  name: string; 
}
interface User extends Name { 
  age: number; 
}

interface Name { 
  name: string; 
}
type User = Name & { 
  age: number; 
}

// 基本类型别名
type Name = string

// 联合类型
interface Dog {
    wong();
}
interface Cat {
    miao();
}

type Pet = Dog | Cat

// 具体定义数组每个位置的类型
type PetList = [Dog, Pet]

// 当你想获取一个变量的类型时，使用 typeof
let div = document.createElement('div');
type B = typeof div

type StringOrNumber = string | number;  
type Text = string | { text: string };  
type NameLookup = Dictionary<string, Person>;  
type Callback<T> = (data: T) => void;  
type Pair<T> = [T, T];  
type Coordinates = Pair<number>;  
type Tree<T> = T | { left: Tree<T>, right: Tree<T> };

interface User {
  name: string
  age: number
}

interface User {
  sex: string
}

/*
User 接口为 {
  name: string
  age: number
  sex: string 
}
*/
