获取 Response.Json() 对象的第一个对象 [重复]

Question

我有这个代码：

fetch("https://rickandmortyapi.com/api/character/?name=Rick")
    .then((response) => {
      response.json().then((data) => {
       console.log(JSON.stringify(data))
    }).catch( (error) => {
        console.log(`Error: ${error}`)
    })
   })

有问题的 api 并不重要，问题是 response.json() 返回一个对象数组，我有点迷路，我想选择某个索引来选择该对象但我不能，我尝试了多种方法，但不工作，不仅仅是一个简单的答案，我想如果它可能解释对象如何与 response.json() 一起工作，如果 javascript 中的简单对象不同，谢谢。

编辑：这是代码的输出

Answer 1

response.json();

在大多数情况下返回一个对象数组，就像任何其他数组一样，您可以解构它以获取第一项

const [first] = data;

类似：

fetch("URL")
    .then((response) => {
      response.json().then((data) => {
      const [anyVar] = data.results; // first index of the array
      console.log(anyVar);
    })
   })
