如何在 typescript 中为数组定义数据类型？

Question

我正在尝试将数组类型定义为基本上如下所示：

[
  {
    name: string,
    comment: string
  },
  {
    name: string,
    comment: string
  }
]

但无论数组中有多少个 cmets，它都需要工作。

我发现了一些像 How to define array type in typescript? 这样的人设置长度的例子

但我无法让它为我正在做的事情工作，这里是上下文：

class Post{
  person: string;
  bird: string;
  content: string;
  image: string;
  comments: Array<MyType>;
  score: number;
  grade: number;
  constructor(p: string, b: string, c: string, i: string = '', cm: Array<MyType> = []) {
    this.person = p
    this.bird = b
    this.content = c
    this.image = i
    this.comments = cm
    this.score = 0
    this.grade = this.score + this.cm.length
  }
}

我应该如何定义类型 MyType？

Answer 1

class Post{
  person: string;
  bird: string;
  content: string;
  image: string;
  comments: Array<{name:string, comment:string}>;
  score: number;
  grade: number;
  constructor(p: string, b: string, c: string, i: string = '', cm: Array<{name:string, comment:string}> = []) {
    this.person = p
    this.bird = b
    this.content = c
    this.image = i
    this.comments = cm
    this.score = 0
    this.grade = this.score + this.cm.length
  }
}

Answer 2

我总是更喜欢interface ovre class

interface Post{
  person: string;
  bird: string;
  content: string;
  image: string;
  comments: Array<Comment>;
  score: number;
  grade: number;
}
interface Comment{
    name : string;
    comment:string;
}
