As far as I know, without Proxy or Object.observe() there would be no possible way to watch for changes *as they happen* and directly fire off an observing function or handler. You need assistance from the JS runtime to track stuff like this correctly and efficiently. The polyfills for O.o() use timers to watch for changes - changes/accesses can be missed between polls. I am happy Proxy is at least staying around - I was initially freaking out thinking Object.observe() was the mechanism behind Proxy's magicalness. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
