I know that you are asking for similarities, but itβs easier to answer what the differences are (from the point of view of users they are not different from each other)

What are the current differences between jQuery and prototype?
A prototype is a mature structure that does a very good job of difference in the browser and providing very well thought out functionality. Unfortunately, this is a bit heavy with its changes to the default Javascript, and it does not see rapid development and does not have a significant ecosystem of plugins.
jQuery is a new framework that is able to use some of the lessons of early javascript frameworks such as Prototype to create something more modular, less intrusive, and significantly more powerful and concise. I still like Prototype, but jQuery DOM manipulation and the plugin ecosystem are just too good to ignore anymore. If I were starting a new project, I would have to go with jQuery because it is similar to where the innovation is happening (at least between these two options).
