There are a plethora of techniques that are often used to defer parsing; however, the simple and preferred technique is to simply Defer loading of JavaScript until it is needed. If this technique isn’t appropriate to use on your page, it is next suggested that you use the attribute where appropriate, which prevents parsing from blocking the initial page load by deferring it until the browser’s UI thread is not busy doing something else. All these settings can be applied with Asset CleanUp Pro Nulled Page Speed Booster without writing any code.
