JS异步获取Promise对象内部数据的正确方法

	const res = getTaskItems({});
    if (res.code === 0) {
    	this.taskItem = res.data;
    }

  getTaskItems({}).then(res => {
      console.log(res.data);
    })

let lyric = getLyric(this.$store.state.songId);
console.log(lyric)

let lyric = getLyric(this.$store.state.songId);
let a = lyric.then((res)=>{
    console.log(res.data)
});
