What does HackerNews think of sizzle?

Tiffin Tom: Fish, chips and a side of identity theft | Jul 2023

jQuery first came-out long before browsers had querySelector: it used a 100% JS reimplementation of a CSS selector parser and evaluator, which was eventually spun-off into its own library: Sizzle.js: https://github.com/jquery/sizzle - Surprisingly, jQuery didn't fully remove Sizzle until 2019 ( https://blog.jquery.com/2019/04/10/jquery-3-4-0-released/ ) - if that seems surprisingly recent, don't forget that querySelector wasn't added to the DOM API until 2013 - with only IE11 supporting it: some places were still using even IE6 well past then, so it makes sense for jQuery to support it for so long.

So using newer CSS selector features, like attribute value selectors, will work fine in post-Sizzle jQuery versions.

If you write JavaScript tools or libraries, bundle your code before publishing | Mar 2016

Are you aware that jQuery bundles Sizzle? I guess not.

Benchmarking Codswallop: Node.js vs. PHP | Nov 2013

> Even if Node was 5x slower than PHP I would still go for Node because of its easy jQuery syntax

That "jQuery syntax" has nothing to do with the language itself. jQuery uses Sizzle[0], which is a CSS selector library for JavaScript. There are plenty of PHP libraries which provide CSS selectors, such as the Symfony CssSelector component[1].

Faster, Better DOM manipulation with Dommy and ClojureScript | Apr 2013

Interesting, but I'm not sure how appropriate it is to be comparing it to jQuery in such a head-to-head fashion such as by saying "15x slower", etc. Does Dommy offer the same features (including the browser support) that jQuery does? If not, then you're just comparing apples to oranges, and it doesn't sound like it does (or even plans to) on account that it sounds like there are design decisions that separate the two with regards to the published API ("Inspired by jQuery, but adapted to be functional in order to better fit with ClojureScript core").

Also, wouldn't it be more accurate for the selector testing to actually test against Sizzle[1]?

Other features aren't even present in jQuery, such as templating, and so I'm not sure why you'd even compare that. Yes people can and do use templates with jQuery, but that's an implementation detail and is not a concern of the library itself; jQuery does not coerce or force you to use a slow templating system, and most any good templating system will also have a compilation step that is run at build-time. So yeah, you can take some ugly userland jQuery example code and make specific code that is faster..
