But reading articles about Front-End frameworks makes me frustrated. Should i pick Vue ? Should i abandon it for React ? Should i pick Angular 1-2 ? What is HNs' advice ?
Don't try to get everything on this hype train, it is not really that important – try to stay simple (like you don't really need this server-side rendering, dedicated state management, don't try to be "functional" – especially funny that not too many understand what it actually means).
So VueJS is absolutely perfect choice, both for simple and middle-complex fields – fast, easy-to-use, declarative, not too verbose. Also don't be afraid to not to use es6 processing through babel (if you target modern browsers like Chrome, a lot of stuff just works there – http://kangax.github.io/compat-table/es6/), or CSS-preprocessors, they are very helpful at scale, but often overkill for small projects.
As for job opportunities, don't think too hard about it. The frameworks that you'll see listed in job ads are pretty much a time shifted image of what was hot three to five years years ago since a lot of projects will have bought into one framework or the other. These days I see a lot of angular 1.x jobs, and some react jobs. In a few years I expect more react. You need solid Javascript knowledge, a lot of curiousity, and just enough buzzwords to get over the threshold, and you'll be all right.
Is Europe that far behind regarding front end frameworks or is JSF the hottest frontend skill in America as well?
LinkedIn has basically taken on this role as they've hired a lot of core Ember devs. Does Google even count if they don't use Angular internally for anything? (so I've heard...)
...opting for its own “Broccoli” build tool instead of industry standards like Webpack
Maybe a good criticism but, no mention of everything being built into ember cli so you don't have to piece together your own mishmash of technologies for every project? This is a serious advantage.
Also, he dismisses the convention over configuration of Ember but doesn't mention the value in a new dev being immediately up to speed on how things should be done. Hell, knowing how things should be done for devs that have been on the same team for years is valuable. Ultimate flexibility just allows you to do things differently every time a new page is developed. This is SERIOUSLY annoying and detrimental to every project.
