The other reploies seem to have answered it! I've never understood why iOS allows JIT inside WKWebView yet not inside bare JavaScriptCore. Maybe because WKWebView runs in its own separate process while a JavaScriptCore instance would run in-process? As for Android, guess Google are just a little more gung-ho?

> thanks for the article. these days it's rare to see something so well researched and written while still being able to tell it was authored by a human. cheers

Really appreciated, thanks! I do despaire that the ease of generating content with AI disincentivises (and discourages) authors from expending real effort, but there's a satisfying inflection point at which you can be sure you've written something that an LLM couldn't possibly have come up with.
