Any way to control Javascript Async Load Order?

If you need a solution for IE9 (since it does not support the defer attribute), I have created a small loader script:

https://github.com/mudroljub/js-async-loader

It loads all your scripts asynchronously and then executes them in order.

You want to use defer if you want to preserve the execution order. What defer does is it async downloads the script, but defers execution till html parsing is done.

<script src="framework.js" defer></script>
<script src="scripts.js" defer></script>

However, you may want to start creating custom bundles once the number of scripts go higher.
