我有如下代码。我想把verse从verses对象中删除。

_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
}
});
});

_self.verses.filter(verse => {
Object.keys(verse).forEach(function(key) {
if(! _self.recieved_translation.includes(key))
{
delete verses[verses];
}
});
});

filter跳过元素，其回调返回false。只需看看是否有问题的键，然后根据布尔值返回。

_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;
});

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