延迟和异步加载JS
defer

异步加载JS：sync

分配器、使用期，释放期


js是单线程语言
首先执行主线程任务，再执行事件队列

<script>
        for (i = 0; i < 3; i++) 
            setTimeout(() => 
                console.log(i)
            , i * 1000);
        
    </script>```
```javascript

axios(
  url:'http://152.136.185.210:7878/api/m5/home/multidata',
  method:'get'
).then(res=>
  console.log(res);
)

axios(
  url:'http://152.136.185.210:7878/api/m5/home/data',
  params:
    type:'pop',
    page:1
  ).then(
    res => 
      console.log(res);
)

axios.defaults.baseURL='http://152.136.185.210:7878/api/m5'
axios.defaults.timeout=5000

axios.all([axios(
  // baseURL:'http://152.136.185.210:7878/api/m5',
  url: '/home/multidata'
),axios(
  
    url:'/home/data',
    params:
      type: 'sell',
      page:5
    
  
)])
  .then(axios.spread((res1,res2)=>
    console.log(res1);
    console.log(res2);
  ))

const instance = axios.create(
  baseURL:'http://152.136.185.210:7878/api/m5/'
)

instance(
  url:'/home/data',
  params:
    type:'pop',
    page:1
   
).then(res => 
  console.log(res);
)
