商品sku数组的实现，最好是用reduce

Question

原始数组，数组不固定，可能有多个，id和name不同，sid可以相同（相同属于同一类）vararr=[{"id":"1","sid":"mm","name":"黑色"},{"id":"2","sid":"mm","name":"白色"},{"id":"3","sid":"xx","name":"64G"},{"id":"4","sid":"xx","name":"128G"},{"id":"5","sid":"yy","name":"normal"},{"id":"6","sid":"yy","name":"plus"}]结果组成vararr2=[{name:'黑色,64G,normal',attrs:[{"id":"1","sid":"mm","name":"黑色"},{"id":"3","sid":"xx","name":"64G"},{"id":"5","sid":"yy","name":"normal"}]},{name:'黑色,64G,plus',attrs:[{"id":"1","sid":"mm","name":"黑色"},{"id":"3","sid":"xx","name":"64G"},{"id":"6","sid":"yy","name":"plus"}]},{name:'黑色,128G,normal',attrs:[{"id":"1","sid":"mm","name":"黑色"},{"id":"4","sid":"xx","name":"128G"},{"id":"5","sid":"yy","name":"normal"}]},{name:'黑色,128G,plus',attrs:[{"id":"1","sid":"mm","name":"黑色"},{"id":"4","sid":"xx","name":"128G"},{"id":"6","sid":"yy","name":"plus"}]},{name:'白色,64G,normal',attrs:[{"id":"2","sid":"mm","name":"白色"},{"id":"3","sid":"xx","name":"64G"},{"id":"5","sid":"yy","name":"normal"}]},{name:'白色,64G,plus',attrs:[{"id":"2","sid":"mm","name":"白色"},{"id":"3","sid":"xx","name":"64G"},{"id":"6","sid":"yy","name":"plus"}]},{name:'白色,128G,normal',attrs:[{"id":"2","sid":"mm","name":"白色"},{"id":"4","sid":"xx","name":"128G"},{"id":"5","sid":"yy","name":"normal"}]},{name:'白色,128G,plus',attrs:[{"id":"2","sid":"mm","name":"白色"},{"id":"4","sid":"xx","name":"128G"},{"id":"6","sid":"yy","name":"plus"}]},]如果vararr=[{"id":"1","sid":"mm","name":"黑色"},{"id":"2","sid":"mm","name":"白色"},{"id":"3","sid":"xx","name":"64G"},{"id":"4","sid":"xx","name":"128G"}]vararr2=[{name:'黑色,64G',attrs:[{"id":"1","sid":"mm","name":"黑色"},{"id":"3","sid":"xx","name":"64G"}]},{name:'黑色,128G',attrs:[{"id":"1","sid":"mm","name":"黑色"},{"id":"4","sid":"xx","name":"128G"}]},{name:'白色,64G',attrs:[{"id":"2","sid":"mm","name":"白色"},{"id":"3","sid":"xx","name":"64G"}]},{name:'白色,128G',attrs:[{"id":"2","sid":"mm","name":"白色"},{"id":"4","sid":"xx","name":"128G"}]},]

Answer 1

按照当前重组对象（就算写在reduce也是一样的，还是纯函数的形式重组你的对象），等于说就是sid一样的抽一个出来，然后重新组成一个对象放到另外一个数组里。大致思路就这样
