Here's how you should do it:

  for(var i=0; i<=3; i++) count(i);

Or a real world example:

  for(var i=0; i<texture.length; i++) createPattern(i);

  function createPattern(i) {
    texture[i].onload = function() {
      pattern[i] = ctx.createPattern(texture[i], 'repeat');
    }
  }

I've made a blog post about closures: http://www.webtigerteam.com/johan/en/blog/closure_en.htm

It would be cool to write like this (but you cant):

  pattern = texture.map(t => t.onload => ctx.createPattern(t, 'repeat'))
