 ### The main idea
 
-The share state is just a tree of objects hosted in a singleton called a store. Any modification on this tree will fire an event inside an event bus. We are going to build this event bus using an Rx [Observable](https://RxJS-dev.firebaseapp.com/guide/observable). You can subscribe to it and unsubscribe from it at any point in time.

 The observable is like a stream of events. Each event is just a string saying "the property A.B.C.D in the shared state have changed".

 ### Protect the shared state
 
-It would be very dangerous to give a direct reference to the share state to the consumer. Remember we want to keep unidirectional data flow. Here some solutions to this problem:
+It would be very dangerous to give a direct reference to the shared state to the consumer. Remember we want to keep unidirectional data flow. Here some solutions to this problem:
 
 - We can clone before delivering the value
 - We can use a library that promote immutable data structures like [immutable.js](https://immutable-js.github.io/immutable-js/)
 
 To keep it simple, we opted to clone the value, even it is slow.

 The ES6 class `GlobalStore` provides the basics of a shared state with an event bus powered by RxJS.
