NGRX/REDUX：通过 json 路径更新深层对象中的值

Question

我有一个对象，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,更新到我拥有的减速器中：return {  ...state,  categories: {    ...state.categories,    Professional: {      ...state.categories.Professional,      active: true    }  }}现在我想编写一个用于扩展对象的函数并通过 json 路径更新单个属性。例如。return deepPatch(state, 'categories.Professional.active', true);该函数的目标deepPatch是在运行时构建此结构：return Object.assign({}, obj, {    categories: Object.assign({}, state.categories, {      Professional: Object.assign({}, state.Professional, {        active: true      })    })});我试过但不知道如何进行递归传播：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;}
