跪求！js 數(shù)組重組根據(jù)配置嵌套結(jié)構(gòu) 形成父子級數(shù)據(jù)求大佬指點！

原數(shù)組如下[[{"name":"VKORG","value":"1000"},{"name":"VTWEG","value":"100"},{"name":"SPART","value":"10"},{"name":"VKORGTEXT","value":"1000text"},{"name":"VTWEGTEXT","value":"100text"},{"name":"SPARTTEXT","value":"10text"}],[{"name":"VKORG","value":"1000"},{"name":"VTWEG","value":"100"},{"name":"SPART","value":"9"},{"name":"VKORGTEXT","value":"1000text"},{"name":"VTWEGTEXT","value":"100text"},{"name":"SPARTTEXT","value":"9text"}],[{"name":"VKORG","value":"1252"},{"name":"VTWEG","value":"100"},{"name":"SPART","value":"10"},{"name":"VKORGTEXT","value":"1252text"},{"name":"VTWEGTEXT","value":"100text"},{"name":"SPARTTEXT","value":"10text"}]]父子關(guān)系是動態(tài)的可配置規(guī)則展示二級或者三級嵌套如['VKORG','VTWEG','SPART']三級或者['VKORG','VTWEG']二級如果形成三級父子級數(shù)組如下[{'value':'1000','label':'1000text','children':[{'value':'100','label':'100text','children':[{'value':'10','label':'10text'},{'value':'9','label':'9text'}]}]},{'value':'1252','label':'1252text','children':[{'value':'100','label':'100text','children':[{'value':'10','label':'10text'}]}]}]如果形成二級嵌套數(shù)組如下[{'value':'1000','label':'1000text','children':[{'value':'100','label':'100text'}]},{'value':'1252','label':'1252text','children':[{'value':'100','label':'100text'}]}]請問下怎么樣根據(jù)設(shè)置的嵌套層數(shù)得到以上結(jié)果###題目描述題目來源及自己的思路相關(guān)代碼//請把代碼文本粘貼到下方（請勿用圖片代替代碼）你期待的結(jié)果是什么？實際看到的錯誤信息又是什么？
