Module

• 關鍵字：export、import

student.ts

export class Student {
  name: string;
  constructor(name: string) {
    this.name = name;
  }
  printName = () => {
    console.log(this.name);
  };
}

export let age: number = 38;

有三種方式：

• import 特定東西

  import { Student, age } from "./student";
  
  let student = new Student("Kappa");
  student.printName();
  
  console.log(age);
• 整個 import

  import * as Student from "./student";
  
  let student = new Student.Student("Kappa");
  student.printName();
  
  console.log(Student.age);
• import 並修改命名

  import { Student as Stu, age as ageTest } from "./student";
  
  let student = new Stu("Kappa");
  student.printName();
  
  console.log(ageTest);
