javascript - 前端大佬们，这段代码如何优化？

Question

    const getSelectedChildFacets = function (parent) {              parent?.childrens?.forEach((child) => {                  if (child.selected && !child.partiallySelected) {                      // 如果是全选                      if (parentValues.includes(child.value)) {                          // 如果是父节点，非子节点则继续向下查找                          getSelectedChildFacets(child);                      } else {                          // 如果是子节点，则存起来                          arrSelectedFacets.push(child.value);                      }                  } else if (child.selected && child.partiallySelected) {                      // 如果是半选，则继续向下查找                      getSelectedChildFacets(child);                  }              });          };

        arrFacetValues.forEach((parent) => {            if (parent.selected && !parent.partiallySelected) {                // 全选                if (parentValues.includes(parent.value)) {                    // 全选且是父节点，向下查找                    getSelectedChildFacets(parent);                } else {                    // 子节点则存到树组中                    arrSelectedFacets.push(parent.value);                }            }            if (parent.selected && parent.partiallySelected) {                // 如果是半选，继续向下查找                getSelectedChildFacets(parent);            }        });

如何将两个方法合并成一个方法

如图parentValues = ['BC', 'BC-SRV', 'BC-SRV-COM'],
想得到的是选中的树组arrSelectedFacets = ['BC-SRV-COM-FTP', 'BC-SRV-COM-TEL']

const arrFacetValues = [                {                  value: "BC",                  selected: true,                  partiallySelected: true,                  childrens: [                    {                      value: "BC-SRV",                      selected: true,                      partiallySelected: true,                      childrens: [                        {                          value: "BC-SRV-COM",                          selected: true,                          partiallySelected: true,                          childrens: [                            {                              value: "BC-SRV-COM-FTP",                              selected: true,                              partiallySelected: false,                              childrens: [],                            },                            {                              value: "BC-SRV-COM-TEL",                              selected: true,                              partiallySelected: false,                              childrens: [],                            },                          ],                        }                      ],                    }                  ],                }              ]

如果 BC-SRV-COM 下的子节点都选中，则arrSelectedFacets=['BC-SRV-COM']

const getSelectedChildFacets = function (node, parentValues, arrSelectedFacets) {    if (node.selected) {        if (!node.partiallySelected && !parentValues.includes(node.id)) {            arrSelectedFacets.push(node.id);        } else {            node.childrens.forEach((child) => {                getSelectedChildFacets(child, parentValues, arrSelectedFacets);            });        }    }};const parentValues = ['BC', 'BC-SRV', 'BC-SRV-COM'];const arrSelectedFacets = [];const arrFacetValues = [    {        id: "BC",        selected: true,        partiallySelected: true,        childrens: [            {                id: "BC-SRV",                selected: true,                partiallySelected: true,                childrens: [                    {                        id: "BC-SRV-COM",                        selected: true,                        partiallySelected: true,                        childrens: [                            {                                id: "BC-SRV-COM-FTP",                                selected: true,                                partiallySelected: false,                                childrens: [],                            },                            {                                id: "BC-SRV-COM-TEL",                                selected: true,                                partiallySelected: false,                                childrens: [],                            },                        ],                    }                ],            }        ],    }];arrFacetValues.forEach((parent) => {    getSelectedChildFacets(parent, parentValues, arrSelectedFacets);});console.log(arrSelectedFacets); // ['BC-SRV-COM-FTP', 'BC-SRV-COM-TEL']
