Ok, that's cool. How long until we're able to use this and not have to worry about browser incompatibilities?
It's nice if you really want to utilize the current syntax, but it's less powerful than either option it's derived from.
It works in every browser today, and even old browsers, INCLUDING IE8!
Am I right in assuming that IE won't receive any more feature updates? Many enterprises will stay on Win 7 for a while and enterprises traditionally embrace IE, so thank you, "new" Microsoft, for pushing things forward.
Safari will likely be the next browser that will be slowest to update, considering its current progress in relation to the latest standards. Even with regular updates they seem to be falling behind.
Well, Windows 7 and 8.1 will receive support until 2020 and 2023 respectively. That gives us at least four years of IE 11 being the "new IE 6." (Yes, that is a bit of an overstatement, I remember the horrors of IE 6 quite well. It's still disappointing.)
But Edge updates seem to be a lot rarer than people expected, and seemingly tied more into Windows updates than any sort of regular release schedule.
If Microsoft want to make it a good browser in the long term, they need to move away from tying updates to Windows ones and just release them when new features have been implemented.
