在JavaScript中从对象中删除值

我有如下代码。我想从

verses

对象中删除

verse

_self.verses.filter(verse => {
    Object.keys(verse).forEach(function(key) {
       if(! _self.recieved_translation.includes(key))
       {
         // I would like to remove this verse from verses                       
       }
    });
});

使用

delete

从obj中删除项目使用

delete

从obj中删除项目

filter

跳过其回调返回的元素

false

。只需查看是否有问题的键并返回相应的布尔值

_self.verses.forEach(verse => delete verse.verse);

_self.verses = _self.verses.filter(verse => {
    // We don't need foreach here, we just need the first key
    var keyWithoutTranslation = Object.keys(verse).find(function(key) {
       return !_self.recieved_translation.includes(key);
    });
    // Now the filter will do the rest
    return keyWithoutTranslation === undefined;
});
