I love Node.js and MongoDB (A database that goes well with Node). I will use it for embedded systems and backends for web apps. I have questions for frontend JS:

1. Which front end JavaScript framework is good for web apps

2. Which front end JS framework is good for PWAs(progressive web apps)

Backstory: I experimented with Javascript. Built lots of things with it. I want to organize my Javascript toolset by seeing which tool is useful when(e.g. use Angular for enterprise, use Vanilla for fun, etc.)
