javascript - Lodash _.pluck怎么了？(What happened to Lodash _.pluck?)

Question

I once used Lodash _.pluck ...I loved pluck...

(我曾经使用过Lodash _.pluck ...我喜欢采摘...)

Realizing Lodash no longer supports pluck (as of Lodash 4.x), I'm struggling to remember what to use instead...

(意识到Lodash不再支持pluck （从Lodash 4.x开始），我很难记住要用什么代替......)

I went to the docs , hit cmd-f, typed 'pluck', but my poor abandoned friend is not even given a proper mention...not even a 'has been replaced by'...

(我去了文档 ，打了cmd-f，输入'pluck'，但是我可怜的被遗弃的朋友甚至没有给出适当的提及......甚至没有'被'取代'......)

Can someone please remind me what I'm supposed to use instead?

(有人可以提醒我，我应该使用什么？)

The Lodash Changelog says it all...

(Lodash Changelog说明了一切......)

"Removed _.pluck in favor of _.map with iteratee shorthand"

(“删除_.pluck支持_.map with iteratee简写”)

var objects = [{ 'a': 1 }, { 'a': 2 }];

// in 3.10.1
_.pluck(objects, 'a'); // → [1, 2]
_.map(objects, 'a'); // → [1, 2]

// in 4.0.0
_.map(objects, 'a'); // → [1, 2]
