如何在JavaScript中创建一个通用函数以所需格式从嵌套对象中提取数据？

问：

所以，这是我从某个地方获得的数据示例。您可以看到有字段（数组）。存储桶也可以嵌套在内部（再次是数组），直到任何级别。对我来说，每个级别和最后一个级别都很重要。我知道嵌套的水平（比如说，直到 3、5 或任何事先）。bucketsbucketskeydoc_count

const obj= {

      "1": {
        "buckets": [
          {
            "2": {
              "doc_count_error_upper_bound": 0,
              "sum_other_doc_count": 3171,

                  "key": "/form/admin/login",
                  "doc_count": 888
                }
              ]
            },
            "key": "404",
            "doc_count": 2052
          }
        ]
      }
    } 
}

预期成果：

[
  ['200', '/hello', 'demo_gg', 856],
  ['200', 'added*', 'bye', 414],
  ['200', '/festive.txt', 'nothere', 118],
  ['404', '/auto/auto.xml', 'dimension', 1435],
  ['404', '/.env', 'cartoon', 34],
  ['404', '/form/admin/login', 'mouse', 8]
]

注意：存储桶可以有任意级别的嵌套，因此每个数组也将水平增加。因此，我需要一个通用函数来用于任何级别的嵌套，直到它停止。谢谢。
