Three developers on my team spent the last 4 years pushing for angular. Four years ago, I was 50/50 on it vs react, so whatever, but if my team's really for it, let's do it.
Fast forward to angular 2, and we're down to two developers who are still for it.
Fast forward to today, I'm down to one angular dev who's still for it, and two of the original three have left for react jobs. Meanwhile, I'm left with a bunch of angular 1 code that needs to be upgraded to angular 2, and a few testing-out-angular-2 projects that are dependency hell.
The only reason I ultimately embraced angular 1 to begin with (above reasons aside), was because it was so opinionated about everything, I could throw it at my weaker developers and say: "just learn the angular way to do it", and there was very little left they could meaningfully screw up. Angular proponents on the team would see it as a point of expertise to teach the "angular way" to more junior devs, and everyone left the day feeling good.
When it comes to Javascript 95% difficulty with writing good maintainable code is ensuring that your team is all writing to a very exact, and consistent quality and style, since there are so many different ways you can write js, and so many potential pitfalls. And if the team all wants to embrace Google's Angular standard, that works for me. Its far easier to be able to point to an ecosystem with an explicit, opinionated way of writing code, than it is to continuously train people on how to write maintainable code otherwise.
But with angular 2, if you haven't been drinking to cool-aid for a while now, it requires so much knowledge just to get running, I can't even have junior devs work on it, without a senior dev who's also an angular fanboy there to make sure everything is set up to begin with. Its absurd. And I'm supposed to sell to the business that we need to migrate all my Angular 1 code to this monstrosity? And then spend time again every 6 months making the necessary upgrades to stay up to date? Get real.
