While loop statements in Javascript.
Using while statements
The while loop statement
-
A while loop statement has the form:
while (expression) { statement; }
-
In a "while" loop, any statements that form the body of the
loop is executed as long as the expression evaluates to true.
<script type="text/javascript"> var count = 0; // initialize the condition while(count < 5) { // test condition still true count++; // body of the loop starts document.write("count: "+count+"<br>"); } document.write("At end Count: "+count+"<br>"); </script>
The do while loop statement
-
A do while loop statement has the form:
do { statement; } while (expression);
-
In a "do while" loop, all the statements that form the body of the loop is executed once
before the evaluation of the expression.
Otherwise, this loop works the same way that "while" loop.
<script type="text/javascript"> var count = 0; // initialize the condition do { count++; // body of the loop starts document.write("count: "+count+"<br>"); } while(count<5) // test condition still true document.write("At end Count: "+count+"<br>"); </script>
