sizzle VS jQuery

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.

Sizzle looks for simple ID selectors and runs them using getElementById, which is much faster than querySelector[All]. That it is still slower is a testament to how much overhead it adds.

In this article, we will implement the auto typing feature using JavaScript and jQuery, as shown in the video below.

Cheerio is your ticket to the world of server-side magic, allowing you to manipulate HTML and XML documents with jQuery-like syntax. It’s perfect for web scraping, data extraction, or just making sense of the mess that is web content. With Cheerio, you get to play around with the DOM, use CSS selectors, and basically do all the cool things you'd do in the browser, but server-side.

NPM packages include a wide range of tools such as frameworks like Express or React, libraries like jQuery, and task runners such as Gulp, and Webpack.

Great reference.

To this date, one of the best well-documented code is jQuery: https://github.com/jquery/jquery/blob/main/src/core/init.js

I learned a lot from looking into the code.
