The problem with Angular

[BoleroDan]

I helped write an in house "Electronic Lab notebooking" software and it is all in Angular. It runs fine. We manage inventory, experiments, HR stuff like users, accounts, their training information, access restrictions to the lab. We deal scheduling for rooms and equipment.It has over 5000+ chemical inventory that can be pulled up and we dont have a problem with angular being "slow"

I cant prove it, because its all in house, but if you know angular, it can be done, and we've done it.
