This is a great thorough description of the process of migrating gov.uk away from jQuery. It sounds like this guide was instrumental in the process—I love that they’re sharing it openly!
Removing jQuery means that 32Kb of JavaScript has been removed from the majority of pages on GOV.UK. GOV.UK is already quite fast to load and for many users this will make no noticeable difference. However, the change for users on a low bandwidth connection or lower specification device will be much more noticeable, resulting in significantly improved page download speed and performance.
You really don’t need jQuery any more …and that’s thanks to jQuery.
Here, the Github team talk through their process of swapping out jQuery for vanilla JavaScript, as well as their forays into web components (or at least the custom elements bit).
Thanks to jQuery, you probably don’t need jQuery. Just look at all these methods that started life in jQuery, that are now part of the standardised DOM API:
remove()prepend()before()replaceWith()closest()In many ways, moving to vanilla JavaScript highlights the ugliness of working with the DOM directly, and the shortcomings of native Element object — shortcomings which Resig solved so incredibly eloquently with the jQuery API.
Having said that, the lessons I’ve learned over the last year have made me a better developer, and the tools built in the process have opened my eyes and given me enough confidence and understanding of vanilla JavaScript that the only scenario where I would personally consider using jQuery again would be a project needing IE8 support.

Don’t get me wrong—jQuery is great (some of the plugins less so) but the decision about whether to use it or not on any particular project should be an informed decision made on a case-by-case basis …not just because that’s the way things have always been done.
These sites help to inform that decision.
A terrific piece by Remy—based on a talk he gave—on when he uses jQuery and, more importantly, when he doesn’t. His experiences and conclusions pretty much mirror my own, but of course Remy is far more thoughtful and smart than I.
Really good stuff.
The JavaScript library that led the way.
Fear of a third-party planet.
The enshittification of React …which was already pretty shitty for users.
Improving performance on The Session.
When it comes to web performance, there are technical issues and then there are human issues.
