People are sometimes confused about exactly what is/isn't allowed and why. It would be simple enough for us to indicate this somewhere on the page. For example https://github.com/Microsoft/TypeScript/issues/4853
is it feasible to be able to pick the version at playground?
or at least provide unique URLs for different versions, with the main one being the current stable release...
not at the time being. but we are planning on cleaning up the website soon, including the handbook, and the playground. and allowing multiple versions has been one of the top requests.
Any updates on this? It would be really nice to be able to select other-than-latest version.
Hit F12 on the playground, you should see the version written to the console.

@mhegazy Okay, but how can I change the version that playground use? :)
