JavaScript inverse string

varstr = "ABCDEFG",        /** Convert string to array by split **/arr= Str.split (""), Newstr=""; Console.log ("Before inversion:" +str)/** Implementation Method **/    functionrevers (arr) {/** Determine if the array is empty **/        if(arr.length>0){            /** Intercept the last of the array and assign a value to the new empty string newstr, and connect as + = **/Newstr+ = Arr[arr.length-1]; /** Overflow The last value of the original array via the POP () method, callback method, and pass in the removed array **/Arr.pop ();        Revers (arr); }} revers (arr) Console.log ("After reversal:" +NEWSTR);
