}

### Subscribe to state modification for a specific path

import {subscribe} from '../lib/redux-subscribe-ts'

let onStateChange = function(stateChange) {
    // stateChange.path: state path
    // stateChange.prev: previous sub-state (corresponding to this path)
    // stateChange.next: next sub-state
    // stateChange.diff: differences between prev/next sub-states
}

// subscribe to 'store.tarifs'
store.dispatch(subscribe('path', 'uniquesubscriberkey', stateChange=>this.onStateChange(stateChange)))
