title: HTML Canvas Interval vs RequestAnimationFrame
body: <p>So, maybe total brainfart here. The syntax for <code>setInterval()</code> is pretty clear. Do something every x miliseconds. How is this best translated to using the <code>requestAnimationFrame()</code> ?</p>
  
  <p>I have about 300 objects and each is supposed to perform an animation sequence at a certain interval (every 8, 6, 2, etc seconds)? How can I best accomplish this using <code>requestAnimationFrame()</code> which gets called ~60 times a second? There is probably an easy answer, I just, for the life of me, can't figure it out. </p>
