jQuery Redirect Code

This wraps a redirect inside jQuery's $(document).ready() handler, so the navigation waits until the DOM has finished loading before firing. It generates the same window.location.replace() or window.location.href call as a plain JavaScript redirect — jQuery itself has no special redirect method, it only supplies the ready wrapper around ordinary browser JavaScript.

This exists specifically for pages already built on jQuery, where a redirect needs to sit alongside other code that already runs inside a ready handler and follow the same pattern for consistency.

You probably do not need jQuery just for this

Redirecting is a single line of plain JavaScript, and it does not need to wait for the DOM the way code that manipulates page elements does — window.location can be set the instant the script runs. If a page is not already loading jQuery, adding the whole library just to redirect is unnecessary weight; the plain JavaScript redirect generator produces the equivalent code with no dependency.
