javascript - 根据现有响应创建新的 json 响应

Question

我有 json 响应，其值为 week1、week2、week3、week4 在 week 键中以及基于类别（meetingHash）和 week wise 的计数。我尝试与 .reduce 合并但没有运气。

如果我有week1 and week2for in ，meetingHash 'Hold/Uncategorized'现在为用户创建 2 行。user Sarathy Devarajumonth may

但我想合并为 { meetingHash: "Hold/Uncategorized", month: "May", UserName: "Sarathy Devaraju", Week1: 2, Week2: 0, Week3: 3, Week4: 0 }

预计为

[{"UserName":"Sarathy Devaraju","month":"May","meetingHash":"Hold/Uncategorized","Week1":2,"Week2":0,"Week3":3,"Week4":0},
          {"UserName":"Priya","month":"May","meetingHash":"Hold/Uncategorized","Week1":2,"Week2":0,"Week3":0,"Week4":0},
          {"UserName":"Sarathy Devaraju","month":"May","meetingHash":"1st Presentation / Meeting","Week1":0,"Week2":1,"Week3":0,"Week4":0},
          {"UserName":"Priya","month":"May","meetingHash":"1st Presentation / Meeting","Week1":0,"Week2":1,"Week3":0,"Week4":0},
