Title: What is the difference between jQuery (YUI/Dojo/Ext.js) and Prototype.js (Mootools)?

Was doing an interview and a candidate tried to convince me that they preferred to use vanilla Javascript because jQuery messed with the prototype. I tried to explain that perhaps they're thinking of Prototype.js and they corrected me, not Prototype.js, but the Javascript native prototypes at which point I realized they had no idea how jQuery worked or the difference between the wrapper frameworks like jQuery/YUI/Dojo/Ext and the frameworks that do extend the JS natives like Prototype/Mootools.
