如何在數組的typecript中定義數據類型？

Question

我試圖定義一個數組類型基本上是這樣的：

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

，但它需要不管有多少評論有數組中工作。

我發現了一套長像這個傢伙How to define array type in typescript?

一些例子，但我不能讓它爲我做什麼工作，這裏是上下文：

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 
    } 
} 

我應該如何定義類型MyType？

Answer 1

我總是喜歡接口OVRE類

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

Answer 2

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 
    } 
}
