Minification is the process of removing all unnecessary spaces from a file. These spaces make the files readable during editing but are not needed by the browser. This can be taken a step further by combining files.

Recommendations
- Remove functionality or plugins not following best practices.
- Combine the contents of all files into just one or two.
