迭代 Javascript 数组并根据条件删除

Question

我想遍历一组单词，查找定义并在未找到定义时删除该单词。

我的代码如下所示；

var words = ["word1", "word2", "word3",]

function Meaning(words){
           const getMeaning = async () => {
  const response = await fetch(`https://api.dictionaryapi.dev/api/v2/entries/en/${words}`)
  const myJson = await response.json()

            for(i = 0; i < words.length; ++i) {
                if(!response[i]){
                    myJson.splice(i,1)
                    console.log(myJson)
                }
            }}

这并没有真正做任何事情。我哪里错了？

编辑以添加上下文

也试过这样；

for(i = 0; i < words.length; ++i)
fetch(`https://api.dictionaryapi.dev/api/v2/entries/en/${words[i]}`).then((response) => {
  if (response === 404) {
    let response = words
    words[i].splice(i,1)
    console.log(response)
  }
  throw new Error('Something went wrong');
})
.then((responseJson) => {
    let response = words
    response[i].splice(i,1)

})
.catch((error) => {
  console.log(error)
});

我可以在找不到定义时打印出 404 错误，但我无法将其从 words 数组中删除

试试这段代码，你需要从响应中检查数组的每个元素

var words = ["word1", "word2", "word3"];

function Meaning(words) {
    const getMeaning = async () => {
        const response = await fetch(`https://api.dictionaryapi.dev/api/v2/entries/en/${words}`)
        const myJson = await response.json()
        let result = [];
        myJson.forEach(element => {
            if(words.includes(element)) {
                result.push(element)
            }
        });

        return result;
    }
    return getMeaning();
}
