Example: a company is using Angular 1 today and looking to modernize their stack. You have been hired, and one of your first tasks is to pick a new framework and convince the rest of the team that it's the best choice. You're thinking about the following options:

1) React 2) Vue 3) Angular 2+ 4) Aurelia

If your preference is 1) or 2), it shouldn't be too difficult, even though it means a complete rewrite or building in-house adapters to migrate gradually. If it's 3), even though similar adapters exist, good luck convincing anyone. If it's 4, you're basically dreaming.
