If you have 5 JS files (including jQuery library) loading in the <code>&lt;head&gt;</code> location and 7 JS files loading in <code>&lt;body&gt;</code> location, you will end up with a total of 3 JS files: jQuery library &amp; jQuery Migrate (they are not combined together with other JS files for maximum performance) in 1 file and the 2 JS files for HEAD and BODY, respectively.
