기존에 사용하던 store, composition API ? 형태로 수정 결과

import { defineStore } from 'pinia';

export const surveyStore = defineStore('survey', () => {
    const surveyList = ref([]);
    const apiResult = ref(0);

    async function fetchSurveyList() {
        try {
            const res = await $fetch(`/backapi/selectList`, {
                method: 'POST',
                body: {
                    mapperName: 'survey.selectSurveyList',
                    params: { surveyId: 1 },
                },
            });
            console.log(res.resMap);

            surveyList.value = res.resMap.reduce((acc, obj) => {
                const { questionId } = obj;
                acc[questionId] = acc[questionId] ?? [];
                acc[questionId].push(obj);
                return acc;
            }, {});
        } catch (error) {
            surveyList.value = [];
            console.log(error);
        }
    }

    return { surveyList, apiResult, fetchSurveyList };
});
