    Safari got a reputation of being "the new IE" a few years ago because it was lagging in standards support. However there's been a lot more progress recently - coinciding with when they started releasing Safari Tech Preview builds. edit: As an example, Safari is 2nd after Chrome in this ES7 support comparison: https://kangax.github.io/compat-table/es2016plus/

    And the answer to that is: generally not for IE 10 & above. Sometimes for IE9. Often for IE8.

    I don't think you would need to polyfill Map: http://kangax.github.io/compat-table/es6/#test-Map or Set: http://kangax.github.io/compat-table/es6/#test-Set I will probably continue to transpile for the moment (till I can check everything). There is also polyfill.io which would only polyfill old browsers.

    Yes, that's surprising. Another es6 compat page: https://kangax.github.io/compat-table/es6/ I'm hoping Chrome steps up its game. It's embarrassing.

    Yep. They're kicking everyone's asses in ES6 feature coverage. All the more impressive when you consider how they came from behind. http://kangax.github.io/compat-table/es6/ I's almost sad that Edge is not cross-platform.

    I'm not sure where the hangup is, but I've found that Edge is fast as hell for initial page startup, but lags behind quite a lot when under heavy load. I've seen the benchmarks but in my experience it just... lags... For example, on the kangax ES6 compatibility table [1]. On chrome clicking a column takes less than a second, on Edge (i'm on an up-to-date Windows 10 machine, no preview stuff) it loads faster than in…

    Yes/no. Code is developing faster than standards update: HTML - HTML 4.0.1 -> HTML5 (14 years) CSS3 - in development since 1998 JS - ECMAScript 3 (1999) -> ECMAScript 5 (2009) -> ECMAScript 6 (2015...ish http://kangax.github.io/compat-table/es6/ ) I think web development is a lot like Perl. It is flexable enough for anyone to write something simple and quick but creating a large maintainable project takes a lot of d…

    And yet it's still not 100% ES5 Compatible, like FireFox and Edge, and still behind Chrome (98% to 99%). http://kangax.github.io/compat-table/es5/ Getting to 100% on ES6 was pleasant, but still a surprise given their track record not just with JS support but with some CSS features too. They're often stragglers, even more so now that Microsoft's browser is getting better.
