It infuriates me when I see people complaining about how slow they think JS/HTML/CSS is as a developer platform, or how terrible it is to use a JS framework, when the real cause of slowdown for 99.9% of the web is garbage like this.

Modern web browsers can preload resources and compile and run JS incredibly quickly. But even the best optimization efforts fail when sites are loading thousands of scripts from hundreds of different domains.

And yet still I see developer advocates from Google on Twitter trying to shame people for using React, blaming them for the web's failure to dislodge native apps. It's utter bullshit.
