什么是`Array<class> ` 在打字稿中是什么意思？

Question

Here is some code that I came across. Why does it say dogs: Array<Dog> and not dogs: Array[Dog] ? Thank you.

class Dog {
  public name: string // leaving out 'public' would work too
}

class PetStore {
  dogs: Array<Dog>

  printAllDogNames(): void
  {
    this.dogs.forEach(dog => {
      console.log(dog.name);
    });
  }
}

It is a generic array, you can read in this link: https://www.typescriptlang.org/docs/handbook/basic-types.html

Array

TypeScript, like JavaScript, allows you to work with arrays of values. Array types can be written in one of two ways. In the first, you use the type of the elements followed by [] to denote an array of that element type:

let list: number[] = [1, 2, 3];

The second way uses a generic array type, Array:

let list: Array<number> = [1, 2, 3];
