var weekdays = ["Mon", "Tue", "Wed", "Thur", "Fri"]; do{   document.write(day);   var day = weekdays.pop();   document.write(day+", "); } while (day != "Wed"); //Output is "Fri, Thur, Wed, "

The while(condition){LOOP_BLOCK} and do{LOOP_BLOCK}while(condition); loops allow you to loop through code until a specific condition occurs. The code in your LOOP_BLOCK is executed each time through the loop.
