vue1.0和vue2.0循环索引使用区别

如果是vue1.0这样写：

<ol>
            <li v-for="todo in todos" @click="delete($index)">
                    {{todo.label}}
            </li>
</ol>
然后：

methods:{
    
    delete:function(index){
        this.todos.splice(index,1);
    }
}
如果是vue2.0这样写：

<ol>
                <li v-for="(todo,index) in todos" @click="delete(index)">
                    {{todo.label}}
                </li>  
</ol>
然后

methods:{
    
    delete:function(index){
        this.todos.splice(index,1);
    }
}
