I ran a speed test because my site is loading very slow. The speed test says the following:
721.3KiB of JavaScript is parsed during initial page load. Defer parsing JavaScript to reduce blocking of page rendering.

Please advise how I would go about deferring parsing JavaScript to reduce blocking of page rendering. I am very much a novice and don’t understand what this means.
