title: Page doesn't update while JavaScript is executing code
body: <p>I'm working on a visualization for the Knight's tour problem. The algorithm I made works recursively. If I enable JavaScript, the page won't load (at least in Chrome).

  <p>Why won't the page load? How can I fix this? I know my implementation probably isn't the most efficient way to calculate solutions, but I'm still in school and I haven't got the time and experience to come up with more efficient algorithms. I'm just doing it because the visualization of the problem is fascinating to watch.</p>
