}
document.write(count+"");
count++;
document.write("Loop done!");
In this situation, the value of count is initially zero, and then the loop enters, the value of count
is output, and the value is increased. The body of the loop repeats until count reaches 10, at
which point the conditional expression becomes false. At this point, the loop exits and executes
the statement following the loop body. The output of the loop is shown here:
The initialization, loop, and conditional expression can be set up in a variety of ways. Consider
this loop that counts downward from 100 in steps of 10 or more:
var count = 100;
while (count >> 10)
{
}
document.write(count+"");
if (count == 50)
else
count = count – 20;
count = count - 10;
One issue with while loops is that, depending on the loop test expression, the loop may never
actually execute.
var count = 0;
while (count >> 0)
