REDUX GIVES YOU THE STORE, DISPATCH AND REDUCERS


###
store holds state
state is 0
click the +1 button
'dispatches an action (which is action and state) to reducer
switch in reducer = if ActionType = type(increment) and payload (1), use the increment switch in the reducer to add 1 to state
state gets send back to store
###

Currying = calling a function with fewer arguments than it expects

Use redux if:
Its gonna be a big project
If its shared
If its persisted




Reducer - how does action change state . SHOULD BE CALLED UPDATER
Action - sent off (dispatched) contain data (payloads)
