advanced patterns when updating array elements in a nested object in Vue.js 3
I've hit a wall trying to I'm working with an scenario when trying to update elements in a nested array within a reactive object in Vue.js 3. I have a reactive state that looks like this: ```javascript import { reactive } from 'vue'; const state = reactive({ users: [ { id: 1, name: 'Alice', roles: ['admin', 'editor'] }, { id: 2, name: 'Bob', roles: ['viewer'] } ] }); ``` I'm trying to update the roles of a specific user based on their ID. Here's the method I'm using: ```javascript function updateUserRoles(userId, newRoles) { const user = state.users.find(u => u.id === userId); if (user) { user.roles = newRoles; // This line seems to not trigger reactivity } } ``` When I call `updateUserRoles(1, ['editor', 'viewer']);`, I expect the roles for Alice to update, but the UI doesn't reflect this change unless I force a re-render. I've also tried wrapping the update in `nextTick()` to ensure the UI updates, but it hasn't solved the question. Additionally, I verified that `user` is not `undefined` and contains the correct reference to the object. I checked the Vue documentation, and it mentions that direct assignment like this should work, so I'm confused. Is there a specific way I should be updating nested properties in Vue 3 to ensure that the reactivity system detects the changes? Or is there a better practice I should follow to handle updates like this? I'm using Vue version 3.2.26 and have not implemented any custom reactivity handlers. For context: I'm using Javascript on macOS. I've been using Javascript for about a year now. Is this even possible?
