How redux-thunk is used is this project

[desis123]

This is not an issue, rather than a question. I am really newbie to react world... I am kind of confused how redux-thunk is used in this project. As far my understanding redux-thunk would create action creator that would return a function with an argument dispatch .. and later on that dispatch argument will dispatch several other actions inside that function ... So my question is how and where redux-thunk played it's role in this project. I am in learning phase.. so any help would be greatly appreciated.
