+Some people dislike [jQuery][] because it isn't really needed for
+modern browsers (see [You Might Not Need jQuery][]).
+
+Many older sites embed multiple versions of [jQuery][], often as a
+[transitive dependency][].
+
+I thought "wouldn't it be funny if there was a page that loaded *all*
+versions of [jQuery][]?".
+
+Behold:
+
+[{{< pe-figure "jqueries" >}}][jqueries]
+
+Notes:
+
+* Embeds every version of [jQuery][] from 1.2 to 3.6.1, including the
+ slim builds.
+* Each version of [jQuery][] animates it's own row. See the [unminified
+ `script.js`][script.js] for details.
+* You may have trouble hosting [jQueries][] if you have a restrictive
+ [`Content-Security-Policy`][csp] ([like mine][min-csp]). In
+ particular, versions of [jQuery][] older than 1.4.0 will fail
+ to load.
+* Deliberately serves up old versions of [jQuery][] with known security
+ vulnerabilities. Be careful where you host this.
+
+Source code, build instructions, and additional details are available in
+the [GitHub repository][repo].
