将对象数组的值拼接成一个句子

如何解决将对象数组的值拼接成一个句子

我有一个如下所示的 api 响应：

"payload": {
    "paragraph": {
        "id": 2692,"words": [
            {
                "id": 21679,"position": 2,"translation": {
                    "text": "something","language_name": "english"
                },"transliteration": {
                    "text": "another","language_name": "english"
                }
            },{
                "id": 21671,"position": 1,"translation": {
                    "text": "Then","transliteration": {
                    "text": "fa",...
        ]
    }
}

如何基于 translation 键从 position 键构建句子。例如，预期的输出应该是一个对象，如：

{line: "Then something"}

解决方法

首先，您需要对 positions 进行排序，然后您可以使用如下地图加入它们。

let words = [
    {
        "id": 21679,"position": 2,"translation": {
            "text": "something","language_name": "english"
        },"transliteration": {
            "text": "another","language_name": "english"
        }
    },{
        "id": 21671,"position": 1,"translation": {
            "text": "Then","transliteration": {
            "text": "fa","language_name": "english"
        }
    }
]

let word = words
       .sort((a,b) => a.position - b.position)
       .reduce((word,w) => `${word} ${w.translation.text}`,"");

console.log(word)
