The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 16.6 kB or 70% of the original size.

    • Original 19.0 kB
    • After minification 15.9 kB
