javascript - typescript中关于类型声明和命名空间的问题

Answer 1

你那么写确实有点问题：

export namespace Namespace {
    export class B {
        constructor() {
            console.log('hello');
        }
    }
}

main.ts

import { Namespace} from './script';

new Namespace.B();

// Classes/Animals.ts
export * from '.\Animals\Mammals';
export * from '.\Animals\Reptiles';
Then import the types from the new module as usual:

// app.ts
import * as Animals from '.\Classes\Animals'

let dog: Animals.Dog;
let snake: Animals.Snake;
Or

// app.ts
import { Dog, Snake } from '.\Classes\Animals'

let dog: Dog;
let snake: Snake;
