# Non-Blocking Javascript

Today I learned that using [inline anonymous function to add Javascript files to DOM will block the `onload` event](http://friendlybit.com/js/lazy-loading-asyncronous-javascript/) until the referenced script is fully loaded. The solution is to attach the function which adds the <`script>` element to the `onload` event.
