Action based functional components

Component

A component is set of 4 pure functions —

1. init: Creates the initial state of the component.
2. update: Is a reducer function.
3. command: Is a command function.
4. view: Takes in the state and other params and returns a virtual dom element.
5. Components are framework agnostic.

export interface Component<State, Params, VNode> {
  init(p?: Partial<State>): State
  update<T>(action: Action<T>, state: State): State
  command<T, R>(action: Action<T>, state: State): Action<R>
  view(e: Hoe, m: State, p: Params): VNode
}

init()

1. Takes in one argument which contains a partial version of the State, ie. all properties are optional.
2. Returns a new version of the State.

function init(p?: Partial<State>): State

update()

1. Its an [update function] that takes in an Action and a State and returns a new State.

 function update (action: Action, state: State): State

command()

1. Its an command function that takes in an Action and a State and returns a new Action.

 function command (action: Action, state: State): Action

view()

1. Takes in three arguments — Hoe, State and Params.
2. Returns a new virtual dom element — VNode.
3. VNode can be anything implementation from [React], [snabbdom] etc.

function view(e: Hoe, s: State, p: Params): VNode
