It probably needs further refinement. I'll update if I find any issues. It's written to handle async loading of JS but you might want to sync load this script first unless you're minifying.

I've found it useful in development. Modern browsers also support async loading of scripts which further enhances the experience.

Changes you make in your JavaScript code often don't actually render to the page immediately. In the interest of speed, the browser often waits until the next event loop cycle to render changes.
