The final winner is prototype, while jquery ranks second.

Of course, it should be noted that this only counts the results of the website homepage and does not enter the website. The specific method of investigation is to use a special tool to search for framework-specific keywords on the website. For example, for prototype, search for the strings "prototype. js" and "/prototype ". In addition, manual checks are performed. For example, for Yui, it is ruled out that only the css framework is used and JavaScript is not used.
