> At the time, it took New Reddit almost 200 milliseconds to collapse a single comment. That is 200 milliseconds of pure JavaScript, with hardly any DOM work in sight. If you care about quality software, your jaw should be on the floor. It is a staggering amount of waste for what should have been a few DOM calls. And you feel it as a user: an ugly, intense hitch.

Many such cases. React is basically synonymous with horrible lag and extreme bloat to me. Its name is the highest form of irony.

I'm really not sure why JS frameworks in general are so popular (except to facilitate easy corporate turnover), when the browser already gives you a pretty complete toolset that's the easiest to use out of any GUI library in existence. It's not low level by any means.

Granted something like an <include html component> feature is desperately missing from the html spec, but there are lightweight solutions for it.
