The CC-Scripts plugin gives Admin users the ability to add custom JavaScript code to every page on WordPress website in the head/footer and/or directly after the opening body html tag. Additionally, you can minify scripts using JSMin php library and/or displaying it selectively using dependencies. The best part is that you can do this from the Admin panel, perfect for those who don’t have the programming skills needed to manually add custom JavaScript code to template files.
