it adds one to the number. for (i=0;i <10;i++){ alert (i); } i++ is a shortcut that means i=i+1 therefore the value of i increases during the loop.

i++ is post increment and ++i is pre increment.Suppose var a=5;a++; Here post increment the value of 5 is assigned to a and incremented by 1; whereas if there was ++a instead of a++ , pre increment the value of a is first incremented and then assigned to a
