我有月份数组,应该在其长度时间内从左向右旋转.将所有旋转数组存储在对象变量中.能否请您提出更有效的方法.

var Month = ["Jan","Feb","Mar","Apr","May","June","July","Aug","Sep","Oct","Nov","Dec"];


 Output looks like:

 monthRotate = {
                      rotate1: ["Feb","Dec","Jan"],rotate2: ["Mar","Jan","Feb"],.
                       .
                       . 
                       .
                      rotate11: ["Dec","Nov"]; 
             }

我试过这个方法.

var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];
var rotate = {};
for (var i=1;i
