I did my best to change zero functional code here, I only changed:

• Type Definitions
• Linting Configs
• Prettier
• Type Definitions in Tests

This is obviously going to be a breaking change, but my hope is that I can start here and build up what we need to ship a 5.0

Approved - thanks @zackerydev!

I would support turning off the short return syntax that caused all the formatting changes, but its not a big deal.
