这两处是我的代码，看下怎么改
/* eslint-disable no-new */
new Vue({
el: '#app',
components: { TodoList },
template: '<TodoList/>'
})
----------------------------------------------------------------------------------------------------------------------------------------------
<script>
import TodoItem from './components/TodoItem'
export default ({
components: {
'todo-item': TodoItem
},
'data': () => {
return {
inputValue: '',
list: []
}
},
methods: {
handleSubmit () {
this.list.push(this.inputValue)
this.inputValue = ''
},
handleDelete (index) {
this.list.splice(index, 1)
}
}
})
</script>
