How to set unique id in v-for loop?

Question

Vue.js

I display elements in a loop using v-for. How can I give the rendered element a unique id attribute?

Answer 1

The code will not need to be understood? At least the structure of the array element was given.
In this case, in the forehead you can do this:

<div v-for="(item, index) in items" :key="index" :id="index"></div>
