将两个JSON对象与underline.js合并

我正在尝试合并以下2个JSON对象，这是Youtube API响应。我试过了

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

但它不能正确地合并。我尝试过u0.flant、0.union、0.defaults，但都不适合我

一,

二,

关于如何实现这一点，我没有研究下划线，但您可以尝试使用普通javascript

Object.assign（{}，object1，object2）

。重复的密钥将被覆盖。希望这有帮助。你期望的输出是什么？所以我将有多组这些，我希望它们像a{[1][2]}，b{[1][2]}，c{[1][2]}一样合并。。。希望没有使用merge的重复数据。{[1][2]}这在JS中不是有效的Obj定义。没有obj中的键，我们不能使用任何数组。这是正确的吗？{1:{..}，2:{…}@risyasin请忽略我给出的语法。这可能更接近。a:{1:{..}，2:{..}，b:{1:{..}，2:{..}。c:{1:{..}，2:{..}}。。。
