Answer 1

You can use --version with the latest versions binary

$ deno --version

OR Use deno shell

$ deno
> Deno.version

Deno.version
{ deno: "1.0.0", v8: "8.4.300", typescript: "3.9.2" }

Or using eval command

$ deno eval "console.log(Deno.version)"
// OR
$ deno eval "console.log(Deno.version.typescript)"

Answer 3

01. deno --version will gives you typescript version, deno version and v8 version

$ deno --version
deno 1.0.0
v8 8.4.300
typescript 3.9.2

02. By using deno shell and providing Deno.version.typescript will gives typescript version directly.

$ deno
> Deno.version.typescript
3.9.2

At the moment of writing the answer, the typescript is bundled in Deno as a Git submodule, which you can find here on GitHub, which has a revision of 551f0dd9a1b57ecd527a665b0af7fc98cd107af6, which in turn corresponds to version 3.9.2.

Although, the question about printing the TypeScript version from deno CLI is a courtesy of Deno developers.
