| // This code is to be used with https://turbo.hotwire.dev. By default Turbo keeps visited pages in its cache | |
| // so that when you visit one of those pages again, Turbo will fetch the copy from cache first and present that to the user, then | |
| // it will fetch the updated page from the server and replace the preview. This makes for a much more responsive navigation | |
| // between pages. We can improve this further with the code in this file. It enables automatic prefetching of a page when you | |
| // hover with the mouse on a link or touch it on a mobile device. There is a delay between the mouseover event and the click | |
| // event, so with this trick the page is already being fetched before the click happens, speeding up also the first | |
| // view of a page not yet in cache. When the page has been prefetched it is then added to Turbo's cache so it's available for | |
| // the next visit during the same session. Turbo's default behavior plus this trick make for much more responsive UIs (non SPA). | |
