Faster JavaScript with Category Theory

Explore how category theory can be applied to JavaScript to improve performance in this JSConf talk. Discover how building two categories and satisfying Functor laws can suggest a new architecture for jQuery, potentially speeding up client-side DOM manipulation. Learn about jQuery internals, category theory concepts like identity and composition laws, and their application to HTML and jQuery. Understand the performance benefits of this approach, including rewrapping, fusion, and simplified manipulation. No prior math knowledge is required to grasp the concepts presented. Find out about potential caveats, escape hatches, and the implications for modular development and minification in jQuery.
