Frozen and sealed objects are both dramatically slower in most JS engines I've tested. In the ones where they're not dramatically slower they are never faster.
The last time I asked on the mozilla and v8 bug trackers I was informed that there is no plan to optimize for these features and that the design of the respective JS engines would make such optimizations difficult anyway. (I find this extremely unfortunate.) -kg On Thu, Feb 14, 2013 at 9:48 AM, Andrea Giammarchi <andrea.giammar...@gmail.com> wrote: > If not, any particular reason these are not, being immutable and > representable similar to a C struct ? > > If they could, any idea which engine is planning to optimize and when? > > Thanks and Best Regards _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
