Documentation

program(render, () => Program): Program

• render: (view: VNode) => void render function which handles the virtual dom interaction
• init: [state, effect?] initial State and optional effect
• update: (message, state) => [state,effect?] update function which returns new state and optional effect
• view: (state, dispatch) => VNode return the snabbdom view representation

program takes a render function and a function which returns a Raj program {init, update, view} and returns a new program, which updates the virtual dom when view is called

display(selector, patch): (view: VNode) => void

• selector the dom selector of the root element (for example 'div#root')
• patch a patch function created by snabbdom.init()

display is an example implementation of a function which creates a render function. it holds internally the reference to oldNode
