我有一個對象，如：{  categories: {   Professional: {    active: false,    names: [      {        id: 1,        name: "Golf",        active: false      },      {        id: 2,        name: "Ultimate Frisbee",        active: false      }  ] }}我想categories.Professional.active用true,更新到我擁有的減速器中：return {  ...state,  categories: {    ...state.categories,    Professional: {      ...state.categories.Professional,      active: true    }  }}現(xiàn)在我想編寫一個用于擴展對象的函數(shù)并通過 json 路徑更新單個屬性。例如。return deepPatch(state, 'categories.Professional.active', true);該函數(shù)的目標deepPatch是在運行時構(gòu)建此結(jié)構(gòu)：return Object.assign({}, obj, {    categories: Object.assign({}, state.categories, {      Professional: Object.assign({}, state.Professional, {        active: true      })    })});我試過但不知道如何進行遞歸傳播：function deepPatch(obj: any, path: string; value: any){   const arrayPath: string[] = path.split('.');   const currObj = null;   for (let i = 0, e = arrayPath.length; i < e; i++) {       const currPath = arrayPath[i];       currObj = obj[currPath];       currObj = Object.assign({}, currObj, ???);   }   return currObj;}
