使用Underscore.js将JSON对象响应合并为一个

Question

我尝试合并以下两个Youtube API响应的JSON对象。

我可能会有数百个视频（＃1和＃2的集合），我希望它们以下列格式合并为一个JSON。

  

*请忽略以下命名和语法，这里仅用于解释。

视频-1：{a：{..}，b：{..}}，视频-2：{a：{..}，b：{..}}，视频-3：{a： {..}，b：{..}}，...

只要第二个响应以设定顺序附加到第一个响应，我就开心了。 不喜欢

{a，a，a，a，a，a}，{b，b，b，b，b，b}

更像是

{a，b}，{a，b}，{a，b}，{a，b}，{a，b}，{a，b}

我已经尝试了

_.values(_.extend(_.indexBy(array1, 'kind'), _.indexBy(array2, 'kind')))

但它并没有以所需的方式合并。还试过_.flatten，_. union，_.defaults，但没有一个适合我。
