Title
Body
One of the webapps I'm working in is made up of many partial HTML files. If the partial requires a JavaScript library such as YUI, the YUI library is included in the partial. When the partials are combined at runtime, the resulting HTML often includes the YUI library several times. <html> ... <script type="text/javascript" src="/js/yahoo/yahoo-min.js"></script> ... <script type="text/javascript" src="/js/yahoo/yahoo-min.js"></script> ... <script type="text/javascript" src="/js/yahoo/yahoo-min.js"></script> ... </html> I've seen strange behavior from including jQuery several times, especially when using AJAX. Why, specifically, is including the same JavaScript library more than once a bad idea? Why does it only sometimes cause problems?
