`Array<class>`在typescript中是什么意思？

class Person {
  name: string;
  age: number;

  constructor(name: string, age: number) {
    this.name = name;
    this.age = age;
  }

  sayHello() {
    console.log(`Hello, my name is ${this.name} and I'm ${this.age} years old.`);
  }
}

const people: Array<Person> = [];

const person1 = new Person("Alice", 25);
const person2 = new Person("Bob", 30);

people.push(person1);
people.push(person2);

people.forEach(person => person.sayHello());
