## Features
* Enforces that the state always needs be updated in **actions**, using the always flag for enforceActions.
* Demonstrates the **toJS** method to convert an observable array to a javascript structure. This is used to render the items in a DetailsList.
* Out-of-the-box MobX **decorators** to keep the code clean.
* **Asynchronous** actions
* MobX **computed** values
* **Typescript** version 3.3.4 using @microsoft/rush-stack-compiler-3.3 for compatibility with the latest MobX version and typings
