ES6學習之...分隔符使用

var list=[];

for(var one of this.state.themeDataList){


 var b=(<List p_w_picpathUrl={Util.serverAddr+'/p_w_picpath?id='+one['_id']} themeData={p_w_picpathList} key={one['_id']}>
 </List>);
  list.push(b);

}

等同於
list=[...this.state.themeDataList].map(a=><List p_w_picpathUrl={Util.serverAddr+'/p_w_picpath?id='+a['_id']} themeData={p_w_picpathList} key={a['_id']}>
   </List>)
