Remove elements from an array in Vue: CRUD

As part of our list application, which is part of our CRUD, we are going to create the delete option, which since it is not necessary to define a component for this option, since we do it directly in the list, we can use anything we can apply a click event, for example, to a button:

<template>
 <div>
   <h1>Listado</h1>
   <router-link :to="{ name: 'create' }">Crear</router-link>
   <ul>
     <li v-for="(a, k) in $root.animes" :key="a">
       <router-link
         :to="{ name: 'detail', params: { anime: JSON.stringify(a) } }"
       >
         {{ a.title }}
       </router-link>
       -
       <router-link :to="{ name: 'edit', params: { position: k } }"
         >Edit</router-link
       >
       <button @click="remove(k)">Eliminar</button>
     </li>
   </ul>
 </div>
</template>

As you can see, we have a remove function, to which we pass the index, but it can also be the id if you are working with a database or a rest api; finally we removed it from our list:

<script>
export default {
 data() {
   return {
     animes: [],
   };
 },
 async mounted() {
   await this.$root.getAnime();
   console.log(this.$root.animes[1].title);
 },
 methods: {
   remove:function(i){
     this.$root.animes.splice(i,1)
   }
 },
};
</script>

And with this, when the element of a reactive component, such as the array, is removed, it is automatically updated from our array.
