GitHub Codespaces
A newcomer to the product flavors worth keeping an eye on is GitHub Codespaces, formerly called Visual Studio Codespaces, which provides cloudpowered development environments. In this case, an environment is considered the backend compute functions associated with software development, such as compiling and debugging. Working with this approach can be done using three possible clients: a browser-based editor, VS Code, or the Visual Studio IDE.
At the time of this writing, Codespaces is currently in beta and more information can be found at https://code.visualstudio.com/docs/remote/codespaces.
The bleeding edge
Like the public preview of GitHub Codespaces, VS 2019 and VS for Mac both have their own preview channels available. These allow developers to see and experiment with features that have not yet been released through the stable public channel. Similarly, VS Code has Insider Edition, a daily build that is essentially equivalent to the preview channels of the other flavors.
