The first code defines a type of props using an object structure with curly braces {}, while the second code defines it using square brackets []. The difference is in how the reference property is defined:

In the first code:

reference?: 
  {
    title: string;
    link: string;
  }[];

reference is defined as an array of objects where each object has properties title and link.

In the second code:

reference?: [
  {
    title: string;
    link: string;
  }
];

reference is defined as an array containing a single object with properties title and link.

The first code allows for an array of objects for the reference property, while the second code expects an array containing only one object for reference. The difference lies in the structure of the reference property.

type Props = {
  reason: {
    id: number;
    title: string;
    description: string;
    reference?: 
      {
        title: string;
        link: string;
      }[];
  };
};

type Props = {
  reason: {
    id: number;
    title: string;
    description: string;
    reference?: [
      {
        title: string;
        link: string;
      }
    ];
  };
};

错误的原因是reference属性的类型不同。在第一个Props中，reference是一个数组，格式如下：

{
   title: string;
   link: string;
}

然而，在第二个Props中，你定义了一个元组而不是数组，这意味着它只包含一个元素。

{
   title: string;
   link: string;
}
