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>
