javascript:如何使用遞迴来展平nodejs中的json檔案

我有一个非常複雜的巢狀json檔案，我需要使用 recursion遍歷它
我需要的是

1. 將最裏面的值分配给它的父键
2. 删除最裏面的键和值
3. 删除空物件

我尝試了很多方法，但是我是javascript世界的新手，無法提出正確的解決方案。 我拥有的json巢狀如下

                "_text": "some value"

                    }
                  }
                }
              }
            }

如下所示，我需要的json還可以帮助我删除空物件

              },

                    }
                  }
                }
              }
            }
