State type inferrence

[shaun-sweet]

Currently the guide has for react components the state type defined up with the props. Instead, I propose its changed to be flipped a bit. For example ->

type ownProps = {}
const initialState = {
  isOpen: false
}

class Modal extends React.Component<ownProps, typeof initialState> {
  state = initialState

this better follows the repositories philosophy of implementation being the source of truth

Sounds good, could be added as an alternative approach to the guide in the Class components section.

@shaun-sweet sure go for it. Please try to keep as much consistency as possible in terms of guide structure and naming/casing conventions across the examples.
