for循环过1秒打印一个index值代码

 function wait(i){
    
    
   return new Promise((resolve)=>{
    
    
    setTimeout(()=>{
    
    
     console.log(i)
      resolve(i)
    },2000)
})
}
async function waitAsync(){
    
    
for(var index=0;index<10;index++){
    
    
 await wait(index);
}
}
waitAsync()
