| Looping |
| |
| break and continue |
| |
These statements are used with in a loop. Break as the name suggests is used to break or terminate the loop in between & continue is to continue the loop breaking it for current loop value. |
| |
| break: |
| This statement breaks the loop & shifts the control out of the loop. |
| |
| continue: |
| This statement breaks the loop for current value and resumes the loop
with new value. |
| |
| |
| Example for break: |
| |
| <html>
<head>
</head>
<body>
<script type="text/javascript">
var count;
for(count=0;count<100;count++)
{
if (count>10)
{
break
}
document.write(" "+count)
}
</script>
</body>
</html> |
| |
| |
| Understanding program: |
| The loop gets terminated because we have kept a condition that if the count is more than 10 than break, break statement will end the loop at that point. |
| |
| Output is: |
| 0 1 2 3 4 5 6 7 8 9 10 |

| Example for continue: |
| |
| <html>
<head>
</head>
<body>
<script type="text/javascript">
var count;
for(count=0;count<20;count++)
{
if (count==10)
{
continue
}
document.write(" "+count)
}
</script>
</body>
</html> |
| |
| Understanding program: |
| As soon as the value of count becomes equals to 10 , the loop gets terminated for
this value and the loop resumes with new value.
|
| |
| Output is: |
| 0 1 2 3 4 5 6 7 8 9 11 12 13 14 15 16 17 18 19 |
