This is a simple test of your ability to use JavaScript. The button below is disabled. You will need to enable it. To make things simple, we'll let you know that the button's ID is "the-button". Also, we have provided a textarea below that you can write your JavaScript in. Once you are done, press the "Run my script" button.
Oh, and this time we've added a small catch. There seems to be a runaway function called "DisableButton" that is being called 100 times per second. That function disables this button again.
