我正在嘗試在切片減速器內的狀態數組中追加/更新一些數據，但是當我嘗試對我感興趣的狀態數組進行操作時，我只得到了一個 javascript 代理console.log。.projects這是怎么回事（我做錯了什么）？import { createSlice } from '@reduxjs/toolkit';const initialState = {  projects: [],};const projectsSlice = createSlice({  name: 'projectsSlice',  initialState: { ...initialState },  reducers: {    addProject(state, action) {      const { project } = action.payload;      const newProjects = [project, ...state.projects];      console.group('add project');      console.log('project: ', project);      console.log('state projects: ', state.projects);      console.log('newProjects: ', newProjects);      console.groupEnd();      state.projects = newProjects;    },    setProjects(state, action) {      const { projects } = action.payload;      state.projects = projects;    },    removeProject(state, action) {      const { projectId } = action.payload;      const newProjects = [...state.projects].filter((project) => project.id !== projectId);      state.projects = newProjects;    },    updateProject(state, action) {      const { project } = action.payload;      const projectIndex = state.projects.findIndex((stateProject) => stateProject.id === project.id);      const newProjects = [...state.projects].splice(projectIndex, 1, project);      console.group('updateProject');      console.log('project: ', project);      console.log('projectIndex: ', projectIndex);      console.log('state projects: ', state.projects);      console.log('newProjects: ', newProjects);      console.groupEnd();      state.projects = newProjects;    },  },});export const { addProject, removeProject, updateProject, setProjects } = projectsSlice.actions;export default projectsSlice.reducer;
