Echo JS 0.11.0

Should probably include examples of useContext and useReducer to round things out, but nice intro.

Function based components and hooks always look like unmaintainable messy code. Also I have yet to come across a project where components are being shared using some cloud service like Bit.dev.
Class components seem to be much more structured, much more "JS-y" in a way.
"In many cases, we are forced to duplicate our logic in different lifecycle methods to implement an ‘effect logic’." - I have yet to see such a thing what "effect logic" would be implemented multiple times to share across components?
