Unfortunately, the words "Deno", "TypeScript", and "removal" made for good headline material, and what was effectively a design document about performance optimization[1] became misinterpreted by many as heralding the removal of TypeScript from Deno, despite the document being updated with a explanatory warning that it was a very deep technical document about a specific part of architecture, and that Deno remains completely committed to supporting TypeScript forever.

No, because TS hints should also be able to translate to runtime savings.

I do find the messaging to be confusing, because what would you think I meant if I talked about the runtime of Elixir or Scala?

This is the marketing line on the front page of the Deno project:

> A secure runtime for JavaScript and TypeScript.

They are using the same term "runtime" to describe JS as well as TS. All replies here by Deno team members use the language "Typescript support" but nobody here is saying TypeScript runtime.
