Security, performance, marketing, and design tools — Jetpack is made by WordPress experts to make WP sites safer and faster, and help you grow your traffic.
The ability to delay loading JavaScript files until user interaction
How
Jetpack Boost doesn't have a feature to delay JavaScript loading until the first user interaction. Similar features exist in plugins like FlyingPress, WP-Rocket, and the stand-alone plugin Flying Scripts.
When running a Google PageSpeed test, sometimes they would also recommend using one of those plugins for opportunities like Reduce unused JavaScript and Reduce the impact of third-party code (I tried to replicate that but I couldn't right now, but I distinctly remember seeing them advertising WP Rocket for this feature a few months ago).
This feature would be incredibly valuable to reduce the performance impact of 3rd party code like Google Analytics and the Meta Pixel.
