Javascript Framework Roundup FYB

This document summarizes and compares different JavaScript frameworks. It discusses the pros and cons of JavaScript, including that it is weakly typed, supports both imperative and functional paradigms, and has no packaging. It also covers reasons to use a framework, such as leveraging community support. Two main types of frameworks are described: Swiss army knife frameworks that provide utilities and widget-based frameworks that focus on components and effects. Popular examples of each type are listed and what problems they aim to solve. Finally, criteria for evaluating frameworks are outlined.
