You aren't proving you are resilient to changes by using one of the most current buzz-word filled frameworks out there for two years. The real test happens when your framework of choice truly becomes obsolete, like with what happened to Angular 1.
Perhaps frameworks don't rust in the sense that they deteriorate in terms of capabilities over time. But that doesn't mean that they don't become obsolete. Especially when you're building a product and trying to stay competitive, all the while all the the innovation surrounding a framework has packed up and left for a nicer camp.
The two-way binding/digest nature has really become our enemy. Everything we write has to account for digests and we've wound up with some terribly ugly code to account for digest problems.
Angular 1 is great for hobbyists and it makes implementing simple forms easy but when you use it for an enterprise app, it hurts.
Our app is still vastly better than decade-old 1.0 we've replaced, but we sure hate the digest now.
Good god. You chose Angular 1 two years ago? As in 2015? When its horrific shortcomings were already known and the Angular devs were working on Angular 2.x?
But I agree, I do not think everyone is jumping ship to Vue (or whatever) over the license.
