Is it possible to avoid unnecessary nesting of div in a template? For example, using a template instead of a div for wrapping during iteration.

Yes, to avoid unnecessary nested divs in the template, you can use the <template> tag. It does not render in the DOM but allows grouping elements for iteration or conditional rendering.

For example, in Vue.js:

<template v-for="item in items" :key="item.id">
  <div>{{ item.name }}</div>
  <div>{{ item.value }}</div>
</template>

Here, <template> serves as a container for multiple elements without adding extra divs to the final DOM. This helps maintain a clean structure and avoid redundant wrappers.
