title: Speed up setInterval
body: <p>I know there's a minimum of 1 millisecond in the setInterval method in javascript. Can I speed this up even more? Like using microseconds?</p>
  
  <p>for what i need this:</p>
  
  <p>i make a canvas css/js animation. it's a simple line, which bends into a cure and back to a line. i have a slider to adjust the speed of this animation. so the lowest slider value would be really fast and the highest really slow. is that understandable? thanks!</p>
