TypeScript语法基础 - 命名空间

export namespace A {
    interface Animal{
        name:string;
        eat():void;
    }

    export class Dog implements Animal {
        name: string;
        constructor(theName: string) {
            this.name = theName
        }

        eat() {
            console.log(`${this.name}吃狗粮`)
        }
    }

    export class Cat implements Animal {
        name: string;
        constructor(theName: string) {
            this.name = theName;
        }

        eat() {
            console.log(`${this.name}吃猫粮`)
        }
    }
}

export namespace B {
    interface
    Animal {
        name:string;
        eat():void;
    }

    export class Dog implements Animal {
        name: string;
        constructor(theName: string) {
            this.name = theName
        }

        eat() {
            console.log(`${this.name}吃狗粮`)
        }
    }

    export class Cat implements Animal {
        name: string;
        constructor(theName: string) {
            this.name = theName;
        }

        eat() {
            console.log(`${this.name}吃猫粮`)
        }
    }
}

//1.ts
//导入命名空间A,B
import {A, B} from '../modules/a'
//命名空间外部使用 A的类
var d = new A.Dog('大黄');
d.eat();//大黄吃狗粮
//命名空间外部使用B的类
var c = new B.Cat('喵喵折');
c.eat();//喵喵折吃猫粮
