Sizzle.jsis a JavaScript library that implements a "CSS selector engine designed to be easily dropped in to a host library." jQuery uses it internally for its CSS selection needs. If you wanted a CSS engine and had no need for all the other JavaScript benefits of jQuery, you could use Sizzle.js separately.
Sizzle.js是一个 JavaScript 库，它实现了“旨在轻松放入主机库的 CSS 选择器引擎”。jQuery 在内部使用它来满足其 CSS 选择需求。如果您想要一个 CSS 引擎并且不需要 jQuery 的所有其他 JavaScript 优势，您可以单独使用 Sizzle.js。

OK, it was actually pretty unclear what sizzle.js was to me. Basically, what it does is allows you to use javascript on 'selectors', that is, classes, IDs, DOM elements, etc... So when you use this in jQuery:
好吧，实际上我还不清楚 sizzle.js 对我来说是什么。基本上，它的作用是允许您在“选择器”上使用 javascript，即类、ID、DOM 元素等......所以当您在 jQuery 中使用它时：
$('div')
That's sizzle.js at work, making that element available to javascript.
这就是 sizzle.js 的作用，使该元素可用于 javascript。
I hope I got that all right :)
我希望我没问题:)

jQuery requires sizzle in order to function. You can take the benefit of a working javascript library.
jQuery 需要嘶嘶声才能运行。您可以利用一个有效的 javascript 库。
