Be careful with terms like "directly" as people seem to get very confused when talking about Deno. "Transparently" may be more accurate. My understanding of the situation right now is that by default, Deno runs TS files by transpiling using SWC, which strips types without checking them, and then sends the result to V8. Optionally you can enable type checking which invokes TSC (with no emission) before SWC. All this is done "magically" from the user's point of view.
