按类型分组多个对象时出现问题

Question

我想根据其type对多个对象进行分组。

我正在尝试将unordered-list-item和ordered-list-item分组到以下结构中的新对象

listObject = {             类型：“列表”，             项目：[当前]           };

当前逻辑将所有有序和无序listItem分组。

现在，我想将类型为accordion-item的对象归为以下结构，

  {
    type: 'accordion',
    items: [...]
  };

如何更新代码以支持将accordion-items分组到期望的结构？

请帮助。

const content = {
  data: {
    areas: [{
      sections: [{
        rjf: [{
            type: "paragraph",
            text: "(API) as early as possible:",
            depth: 1,
          },
          {
            type: "unordered-list-item",
            depth: 1,
            text: "To your travel agent",
            inlineEntityRanges: []
          },
          {
            type: "unordered-list-item",
            depth: 1,
            text: "During online check-in, from 24 hours up to 1 hour before departure.",
          },
          {
            type: "paragraph",
            text: "\nThe API data includes:",
            depth: 0,
          },
          {
            type: "unordered-list-item",
            text: "Family name and first name",
            depth: 1,
          },
          {
            type: "accordion-item",
            sections: [{
                type: "accordion-title",
                value: "accordion-title1",
                rjf: []
              },
              {
                type: "accordion-body",
                value: "accordion-body1",
                rjf: []
              }
            ]
          },
          {
            type: "accordion-item",
            sections: [{
                type: "accordion-title",
                value: "accordion-title2",
                rjf: []
              },
              {
                type: "accordion-body",
                value: "accordion-body2",
                rjf: []
              }
            ]
          }
        ]
      }]
    }]
  }
};


function contentDataMapping(data) {
  const areas = data.areas;
  const listItemTypes = ['unordered-list-item', 'ordered-list-item'];
  return areas.map(area => {
    return area.sections.map(section => {
      let lastHeadingIndex = -1;
      return section.rjf.reduce((acc, current, index) => {
        if (!current.type || !listItemTypes.includes(current.type)) {
          lastHeadingIndex = acc.length;
          return [...acc, current];
        }
        let listObject = acc.find((el, i) => i > lastHeadingIndex && i < index && el.type === 'list');
        if (!listObject) {
          listObject = {
            type: 'list',
            items: [current]
          };
          return [...acc, listObject];
        }
        listObject.items = [...listObject.items, current];
        return acc;
      }, []);
    });
  });
}

console.log(this.contentDataMapping(content.data));

当前结构

      {
        "type": "accordion-item",
        "sections": [
          {
            "type": "accordion-title",
            "value": "accordion-title1",
            "rjf": []
          },
          {
            "type": "accordion-body",
            "value": "accordion-body1",
            "rjf": []
          }
        ]
      },
      {
        "type": "accordion-item",
        "sections": [
          {
            "type": "accordion-title",
            "value": "accordion-title2",

          },
          {

            "rjf": []
          }
        ]
      }

预期：

        ]
      }
    ]
