>I'm happy for competition in this space, specially because Deno can run true TypeScript directly and not just strip types like the current Node implementation.

this is misleading. there is no "running true ts". you will always be running pure js (until someone actually develops a "true" ts engine), and deno does "type stripping" just the same. the only difference is that it bundles the tools and makes it transparent and config-free which is more convenient (although more rigid).
