How do you stop an infinite loop? Tutorial crashed my browser (and this lesson).

Hello Justine Jordan;

Let's say I want to print the phrase "Hello World!" ten times. This is how I'd do it using while loop

        var count = 0;

        while (count < 10) {
            document.write("Hello World!<br>");
            count++;    
        }

first I created a variable named count and assigned the value 0 to it

Then, the while loop will check if the value in "count" is less than 10. If the value is less than 10, then the code inside the while loop will be executed. Next, I'll increment the value in count by 1 using

count++;

OR

count = count + 1;

OR

count += 1;

All of them are correct.

Note if you don't increment the value in "count", you'll be stuck in an infinite loop.

I hope that helped

Hi Justine,

I recommend to use timer (SetTimeOut function) to implement your infinite loop.

The below link is an example:

Browsers will be dead if using 'for' loop or 'while' loop implements infinite loop. What will have to be done in this situation is just to close or Force Quit browsers.

Hope this is useful for you question.

Thanks!

Hi Justine, the only thing you could do is quit or force quit your browser and start again. That part of the tutorial is to show you a loop could go on forever and will crash your browser. I just watched him do it but skipped doing that :)

press (ctrl + shift + esc) if on windowsOS to open the task manager then right click your browser icon Chrome ,fireFox and then click 'End Task'.

Right before I hit refresh I told myself not to execute this because I knew it would crash my browser... And still I executed it... not sure when my hands had a mind of their own but yea I feel your pain. I just force closed my browser.

you can close console (by clicking on x right side of console) and then reopen it by clicking on 'view' and then 'show console'.
