Flying Scripts: Delay JavaScript to Improve Site Speed & Performance

Download and execute JavaScript on user interaction.

Demo video

Flying Scripts delay the execution of JavaScript until there is no user activity. You can specify keywords to include JavaScripts to be delayed. There is also a timeout which executes JavaScript when there is no user activity.

Why should I use this plugin?

JavaScript is very resource-heavy. By delaying the execution of non-critical JavaScript (that are not needed for the initial render), you're prioritizing and giving more resources to critical JavaScript files. This way you will reduce render time, time to interactive, first CPU idle, max Potential input delay etc. This will also reduce initial payload to browsers by reducing the no. of requests.
