While the comment is technically accurate, it's: (a) worded as a contradiction to the parent comment but isn't (it just talks about something unrelated - runtime typechecks). Deno does run typescript code out of the box, typechecks aside. (b) the technical accuracy isn't particularly significant/relevant since in practice Deno has a simple switch to check types on run (though I'm not sure why you would want to do that outside of a development environment: Typescript is a static tool & doesn't have any dynamic capabilities that would change results based on runtime environment).
