On June 17, 2011, John Roberts introduced CDNJS Selections, a selection of scripts from the full CDNJS collection hosted on CloudFlare's global CDN. The open-source repository features community-driven projects and is highlighted by five JavaScript libraries that help site owners deal with legacy browsers: Modernizr, Google Chrome Frame, Flexie, CSS3 Finalize, and JSON2. These scripts can be added to a website using the CDNJS Selections App without any code changes.
