When should you add the defer attribute to the script element? (on Go Make Things)
For many years I’ve placed script elements just before the closing body tag rather than in the <head>. Since a standard <script> element is render-blocking, the theory is that by putting it at the end of the document – after the main content of the page has loaded – it’s no longer blocking anything, and there’s no need to wrap it in a DOMContentLoaded event listener.
It turns out that my time-honoured default is OK, but there is a better approach.
