mouse tracker dot js

where's the mouse at?

var mouse = mouseTracker();

now mouse.x and mouse.y stay updated! they're initially set to null.

that's basically it!

you can also set what element to bind to.

var mouse = mouseTracker({
  element: document.querySelector('canvas')
});

if you don't like that the starting values being null:

var mouse = mouseTracker({
  startX: 100,
  startY: 200
});
