Regarding Wordle specifically, this allowed Josh Wardle to make the app a simple webpage with no backend necessary beyond serving the page itself. Is there something that allows someone like him to do that aside from LocalStorage?
I believe he could have used Cookies instead of LocalStorage. The data he's keeping seems simple enough. It has the same issues the author is talking about, but it should work.
Sure, but the same caveats generally apply; cookies are limited to a single browser on a single device.
Fair enough. I was more interested in identifying other ways of technically achieving the goal of local storage than solving the authors complaint.
Can client-side code set the cookies themselves? I was under the impression cookies were a HTTP-level thing.
