假设我有一个格式为[Object object, Object object ...]
的对象
其中每个对象的格式为{word: blah, word2: blahblah}
我知道我可以将这个词和标签更改为其他类似的内容
({text: o.label, weight: o.count} for o in data)
但是,我想将其更改为
{blah: blahblah}
删除标签并将每个单词放在一个关键位置,并将blahblah中每个单词放在一个值

我认为你不能理解,但reduce
有效:
data = [
{key: 'hello', value: 'world'}
{key: 'foo', value: 'bar'}
]
result = data.reduce(
(obj, item) ->
obj[item.key] = item.value
obj
{}
)

data = [{word: 'blah1', word2: 'blahblah1'},
{word: 'blah2', word2: 'blahblah2'}]
y = {}; for o in data then y[o.word] = o.word2
y
# { blah1: 'blahblah1', blah2: 'blahblah2' }
如果您手头有underscore
,也可以使用:
_.object([o.word,o.word2] for o in x)
虽然这相当于:
y={}; y[z[0]]=z[1] for z in ([o.word,o.word2] for o in x)
