I've been away from JS for about 10 months and... cool, but, fuck, that changed quickly. Time to get caught back up to speed. Is ES6 now actually viable, in that it's supported by most users' browsers? If not, are there popular compilers for ES5?

"Everyone" is using Babel now. A lot of ES6 features are making their way into browsers and node, but there's so much variation that a transpile step is needed. Babel is nice but currently quite slow. Babel has a REPL you can play with here: http://babeljs.io/repl/#?experimental=true&evaluate=true&loose=false&spec=false&code= http://babeljs.io/repl/#?experimental=true&evaluate=true&loo...

  In this side of the galaxy still looks like JSF with RichFaces and ASP.NET WebForms.

  There's currently a issue for "speed": https://github.com/babel/babel/issues/1486 https://github.com/babel/babel/issues/1486. Looks like it complied ember core from 50s to 18s now.

    Yep, saw that. I don't think it's enough of an issue to not use Babel (my team uses it and we all think it's great), but it is suboptimal.

  Whoa, thanks for introducing me to Babel. It looks like user plugins could be wildly, astonishingly powerful for doing compile-time code execution.

    Correct. One of my favourite at the moment is `babel-plugin-rewire`, which is a neat replacement for `rewire` -- allowing easy unit testing in full isolation by hijacking the `import` statements :) [0] https://www.npmjs.com/package/babel-plugin-rewire https://www.npmjs.com/package/babel-plugin-rewire [1] https://www.npmjs.com/package/rewire https://www.npmjs.com/package/rewire

      Just started using that yesterday, and it's lovely.

You can use Typescript as well for an alternative to Babel, it doesn't have all the features Babel has (like async/await) but they are planned. And you get types at the same time.
