SharePoint Framework web part which uses [Redux](http://redux.js.org/) to maintain a single state for the entire application and [ImmutableJS](https://facebook.github.io/immutable-js/) to create performant state trees.
Redux AJAX actions are used together with the SharePoint REST API to display lists in your site. You can also add a new list to the site from this web part.

Every [Redux](http://redux.js.org/) action creates a copy of the state, changes the required properties in the copy and then returns the copy as a new state. This prevents bugs where the state is changed unknowingly.
On the other hand, this can also be performance intensive as for changing only a single element, we have to copy the entire state tree in memory. Fortunately, [ImmutableJS](https://facebook.github.io/immutable-js/) comes to the rescue here.
Using ImmutableJS, we can create new state trees in memory without duplicating the elements which are unchanged. When you create a new state object using ImmutableJS, the new object still points to the previous memory locations of unchanged elements. Only the properties which are changed are allocated new memory locations.
