This is an example of a beat. When the page body loads, the beat will cause the page to emit a one second beep every three seconds.

//<3 Beat
//In general, every beat will define what hearts are called in the HTML body.
<body3
//It's good practice to not redefine global methods in the body, just in case
//you want to use the default values in another heart. That's why we're def-
//ining our beep and tick inside a nested heart, called threeBeep.
<threeBeep3
//We define the beep method's properties by putting it in a heart.
<beep3
//Set frequency and time
440. => freq;
1::second => time;
</3
//Set up the three second ticker.
<tick3
//Time is three seconds.
3::second => rate;
//Every tick, we need it to beep, so...
^beep;
</3
//Lastly, set up the ticker...
^tick;
