将重复的PHP属性重构为JS

Question

我在重构一些旧的PHP代码，并且有一些类似的重复代码行，它们使用相同的属性：

$new_artist["spotify"]["current"]["total_streams"] = $track["spotify"]["current"]["total_streams"];
$new_artist["spotify"]["current"]["total_listeners"] = $track["spotify"]["current"]["total_listeners"];
$new_artist["spotify"]["current"]["source_of_stream"] = $track["spotify"]["current"]["source_of_stream"];
$new_artist["spotify"]["current"]["access_type"] = $track["spotify"]["current"]["access_type"];
$new_artist["spotify"]["current"]["metrics"]["new_collection_listeners"] = $track["spotify"]["current"]["metrics"]["new_collection_listeners"];
$new_artist["spotify"]["current"]["metrics"]["spotify_playlist_placement"] = $track["spotify"]["current"]["metrics"]["spotify_playlist_placement"];
$new_artist["spotify"]["current"]["date"] = $track["spotify"]["current"]["date"]; 

要么

$new_artist["spotify_metadata"]["artist_followers"] = $track["spotify_metadata"]["artist_followers"];
$new_artist["spotify_metadata"]["artist_genres"] = $track["spotify_metadata"]["artist_genres"];
$new_artist["spotify_metadata"]["artist_popularity"] = $track["spotify_metadata"]["artist_popularity"];
$new_artist["spotify_metadata"]["artist_images"] = $track["spotify_metadata"]["artist_images"];

我可以像这样重构

const newArtist = new_artist["spotify"]["current"];
const spotifyCurrentData = track["spotify"]["current"];
newArtist["total_streams"] = spotifyCurrentData["total_streams"]

但我需要为每个新属性创建一个新变量，想知道有人提出一些建议吗？ 我考虑过只编写一个接受属性并从给定数组中提取值的函数

为什么不只是在服务器端合并数组并将其加载到您的javascript中呢？

$new_artist["spotify_metadata"] = array_merge(
    //Any original content
    $new_artist["spotify_metadata"],
    //Any new content from $track
    $track["spotify_metadata"]
)

在JavaScript中，您必须遍历键并分配它们：

var newArtist = new_artist["spotify"]["current"];
var spotifyCurrentData = track["spotify"]["current"];

for (const key in spotifyCurrentData) {
    if (spotifyCurrentData.hasOwnProperty(key)) {
        newArtist[key] = spotifyCurrentData[key];
    }
}
