API:

import createStore from 'brenton-store'

createStore( initialState )

const initialState = {
    foo: {
        bar: 'baz'
    }
}

const store = createStore(initialState)

store.getState()

store.getState().foo // === { bar: 'baz' }

store.getStateAt(path);

store.getStateAt(['foo', 'bar']) // === 'baz'

store.subscribe(type, handler)

store.subscribe('EVENT_TYPE', (nextState, prevState) => {
    console.log(nextState, prevState)
})

subscribeReference.unsubscribe()

const ref1 = store.subscribe('EVENT_TYPE', (nextState, prevState) => {
    console.log(nextState, prevState)
})
const ref2 = store.subscribe('EVENT_TYPE', (nextState, prevState) => {
    console.log(nextState, prevState)
})
const ref3 = store.subscribe('EVENT_TYPE', (nextState, prevState) => {
    console.log(nextState, prevState)
})

// deletes the eventHandler for ref2
ref2.unsubscribe()

store.emit(type)

// calls all eventHandlers subscribed to 'EVENT_TYPE'
store.emit('EVENT_TYPE')

store.update(type, payload)

const payloadToReplaceState = { foo: 'foo' }

// calls all eventHandlers subscribed to 'EVENT_TYPE'
// and replaces state with payload
store.update('EVENT_TYPE', payloadToReplaceState)

store.getState() // === { foo: 'foo' }

store.updateAt(path, type, payload)

const payloadToReplaceValueAtEndOfPath = ['sandwich']

// calls all eventHandlers subscribed to 'EVENT_TYPE'
// and replaces state.foo with payload
store.updateAt(['foo'], 'EVENT_TYPE', payloadToReplaceValueAtEndOfPath)

store.getState() // === { foo: ['sandwich'] }
