> it's jquery[0], so this is only the "old days" if 2006 was the "old days" for you People don't remember so well. Even backdating it that far is too generous. Just as a reference point, on New Year's Day 2006, jQuery didn't even exist yet. There was a time post-2010 when the scourge of jQuery showing up for trivial use cases was considered a real problem and a huge source of bloat on the web. (Side note: it's more than a little annoying, for this reason, to see people when trying to talk about changes in Web developer trends to lump jQuery and vanilla JS together.) To give another reference point, Firefox's then-new Tab Groups feature demanded the creation of a jQuery-like library for handling the tab canvas. John Resig was a longtime friend of the project and one-time Mozilla Corporation employee, but jQuery itself was out of the question because of bloat/performance. That was for Firefox 4, which would have been 2011, since it was released at the end of Q1 that year... There's a lot more concentrated change in the 2010―2015 timeframe than is often accounted for when people think or talk about the Web.
