If one thinks all they need to do is remove javascript to speed things up substantially, then they fit into my category of people who only know jQuery snippets only think they know enough.
There are a multitude of issues that can be tweaked to speed things up more so than javascript elimination. You can switch to HTTP/2, implement server push, image compression, header compression, compressing HTML/CSS/Javascript downloads, preloading, above-the-fold downloads, and much more. A jQuery plugin user might not know half those things and I only mentioned maybe half the things one should know.

- sureaboutthis 8y agoThat is a business and design problem not a programming problem. And if one thinks the functional part of a web site cannot be tuned to substantially increase the speed of a web site then one is part of that jQuery plugin crowd who does not know or understand the pipeline from browser to network to server and back.
- TeMPOraL 8y agoWebsite performance will be limited by the parts you're not allowed to improve, i.e. ad & tracking junk. It's basically Amdahl's law. I'd thought understanding that would be even more important.
