如下所示，怎么将该对象数组根据createDate降序排序？createDate为Date类型。代码越简短越好

let arr = 
    [
        {  
            rule:"1edwe",
            createDate: "2021-01-26T03:28:00.000+0000"
         },
         {  
            rule:"1edwe",
            createDate: "2021-01-26T03:35:34.000+0000"
         },
         {  
            rule:"1edwe",
            createDate: "2021-01-26T03:22:00.000+0000"
         },
         {  
            rule:"1edwe",
            createDate: "2021-01-26T03:26:00.000+0000"
         },
     ]

arr.sort((a,b)=>new Date(b.createDate) - new Date(a.createDate))

arr.sort((a,b) => new Date(b.createDate)-new Date(a.createDate))
