處理 javascript 數組以在谷歌圖表中使用（展平數組內的天數）

Question

我有這個數組

[
  ["04/21/2021", 405, 85, 30]
  ["04/18/2021", 350, 135, 30]
  ["04/16/2021", 335, 120, 30]
  ["04/15/2021", 420, 100, 30]
  ["04/15/2021", 405, 85, 30]
  ["04/15/2021", 350, 135, 30]
  ["04/14/2021", 350, 135, 30]
  ["04/14/2021", 405, 85, 30]
  ["04/14/2021", 405, 85, 30]
]

我不知道如何讓它看起來像這樣

["04/21/2021", 405, 85, 30]
["04/18/2021", 350, 135, 30]
["04/16/2021", 335, 120, 30]
["04/15/2021", 1,595, 420, 120]
["04/14/2021", 1160, 305, 90]

我想刪除重復的天數並將它們放入一個數組中，然后再刪除它們
