In a script element in the body give the JavaScript code for the following:

A for loop that loops 7 times and prints out: 0 1 2 3 4 5 6.

A while loop that loops 7 times and prints out: 2 4 6 8 10 12 14.

Hint: you can increment your iterator by more than just 1.

A do while loop that loops 6 times and prints out: 1 2 3 4 5 6.

A for loop that loops 7 times and prints out: 1 4 9 16 25 36 49.

Hint: use the Math.pow(x,2) method in the body of the loop.

Solution

<script>

var i;
for (i = 0; i <=6; i++) {
document.write(i);
}

i=2
while (i <= 14) {
document.write(i);
i = i + 2;
}

i = 1;
do {
document.write(i);
i++;
}
while (i < 6);

for (i =1; i <=6; i++) {
document.write(Math.pow(i,2));
}

</script>
