如何合并两个文件夹树

Question

我需要将文件夹树“ lhsTree”合并到文件夹树“ rhsTree”

如果rhsTree上没有任何文件夹，我必须通过caomparing从lshTree添加它。最佳/简便的方法是什么？

这是我到目前为止所做的

    for(let i = 0;  i < rhsTree.length; i++){
if (previewItem.label == treedataItem.label) {
              treedataItem.children.forEach((child) => {
              child.wstype = "previewfoldernoid";
              previewItem.children.push(child);
            });
            previewItem.wstype = FOLDER_ICON_TYPE.plainFolder; 
            previewItem.applyState = FOLDER_APPLY_STATE.reddot;
          }
        }

这样，我可以更新父元素的文件夹图标。我也需要在子级上更新Foldericon

输出json
