WP JS Wordpress plugin Allows the developers to compress (using JSMIN algorithm and GZIP) JavaScript files as well as concatenate them into a single file easily. This will make websites faster and improve the user’s experience. Cache expiry time is can also be set in the admin page.

Let’s say we have the famous prototype and script.aculo.us JavaScript libraries. This is in total of 8 files and 247KB files size. Lets say we GZIP each file separately this turns the total into 63KB (74% decrease), which is a good decrease in size. However the user would still have to download 8 files. WP JS turns the files into a mere 45KB (82% decrease) download for the user. This plugin allows you push JavaScript development in terms of modularization and download sizes for Wordpress.
