We'll be focusing the two main components of the Code PlayGround: SDKs and Reactive Code Samples. Developers love SDKs  —  simply because SDKs lift heavy burden of communicating with an API, and let developers focus on the app design and business logic. On the other hand, Code Samples provide the quickest way to the first “Hello World” application. Combine both as a Code PlayGround, and you’ll get developers up and running with your API within no time.
