` to toggle them together. However, this introduces unnecessary wrapper elements into the DOM.
To avoid this, you can use `v-if` on a `` element. The `` tag acts as an invisible wrapper and will not be rendered in the final DOM.
```html
{{ user.name }}
```
* **Correct Solution (Using Computed Properties):**
Filter the list in a computed property before rendering:
```javascript
computed: {
activeUsers() {
return this.users.filter(user => user.isActive)
}
}
```
```html
{{ user.name }}

``` --- ## Key Considerations & Best Practices ### 1. `v-if` vs. `v-show` * **`v-if`** is "real" conditional rendering. It ensures that event listeners and child components inside the conditional block are properly destroyed and re-created during toggles. It has **higher toggle costs** but **lower initial render costs**. * **`v-show`** always renders the element and keeps it in the DOM; it merely toggles the CSS `display` property. It has **higher initial render costs** but **very low toggle costs**. * **Rule of Thumb:** Use `v-show` if you need to toggle something very frequently, and `v-if` if the condition is unlikely to change often at runtime. ### 2. Avoid Using `v-if` with `v-for` on the Same Element When used on the same element, `v-if` has a higher priority than `v-for`. This means the `v-if` condition will not have access to variables from the `v-for` scope. * **Incorrect:** ```html
