Saw a 2 man team that got features done in a couple of weeks on jquery move to angular and turn into a 15 man team that took months on each feature.

Management was very happy with how modern the stack felt

Sales came to a halt for 2 years since features came to a halt.

Turns out Angular is freaky hard to do right.

My old company did the jquery to angular conversion when angular was still alpha. Initial curve was steep because no one was used to doing things that way. After that we were just as quick if not a little quicker. I did a pretty big angular 2 e-commerce site from scratch by myself in 6 months shortly after angular 2 came out. Just use the framework how it's supposed to be used and it all works fine.

on the other side, we went from jquery messes with a bunch of state machine issues to being able to comfortably add client-side interactivity with a lot less worries when moving to Angular 1.x

There were definitely Angular-related issues, but they were replacing a lot of "my state machine is out of sync" issues that just scopes and watching mostly solve (except for the prototype inheritence gotcha)

I rebuilt my company's homepage and SaaS customer area from scratch in half a year, after the old 20 people jQuery team had been stuck for months implementing framework-like features with no useful progress.

I guess whether or not you'll be productive with Angular depends a lot on your experience and expectations. I come from the C++ world and Angular felt like MFC, so oddly familiar.

A family member works at a software company that’s worth ~100MM less than it should be right now because they let Angular get into too much of their app before they settled on Vue.

My company is in the process of jQuery to React transition. It feels like it's taking a little longer as well.

Was this AngularJS (i.e. Angular 1) or Angular 2+? I could believe it either way, just curious.

Angular 5-7

I can believe this
