I&#x27;m fine with that.. however, I&#x27;ve seen <i>MANY</i> instances of websites that load multiple versions of jQuery... that&#x27;s just one library.  Let alone how poorly constructed most web applications are.<p>When it comes down to it, for so long many front-end guys only cared about how it looked, and backend guys didn&#x27;t care at all, because it&#x27;s just the ui, not the <i>real</i> code.<p>We&#x27;re finally at a point where real front end development is starting to matter.  I honestly haven&#x27;t seen this much before about 3-5 years ago... which coincides with node and npm taking over a lot of mindshare.  There&#x27;s still a lot of bad, but as the graph show, there&#x27;s room to make it better.
