JavaScript For Loop


Hello guys! afternoon and welcome to this new tutorial post on JavaScript. In my last tutorial post i talked about JavaScript while loop, now let's quickly take a look at another form of loopingcalled for loop.

The for loop is the most compact form of looping. It is made up of three important parts which are listed out below:

  • The text statement which will text if a given condition is true or not. If the condition is true, then the code given inside the loop will be executed, otherwise the control will come out of the loop.
  • The iteration statement where you can increase or decrease your counter.
Note: you can put all the three parts in a single line separated by semicolons.

You can check out our tutorial post on: JavaScript Operators

Flow Chart

Below is the flow chart of JavaScript for loop statement.


Syntax

The syntax of for loop in JavaScript is as follows:

for   (initialization;    test condition;   iteration statement)  {
       Statement(s) to be executed if test condition is true

               <!--
                    var   count; 
                    document.write("Starting Loop " + " <br />");

                    for ( count = 0;    count  <  8;    count++)  {
                           document.write("Current Count: "  + count); 
                           document.write("<br />");
                    }
                    document.write("Loop stopped!");
               //-->
          </script>
     </body>
</html>

You can try the above example with your text editor for better understanding. Also feel free to drop your questions in the comment box, they will be attended to as soon as possible.

Below is the output of the above example:

Starting Loop

Current Count:  2
Current Count:  3
Current Count:  4
Current Count:  5
Current Count:  6
