That's an objectively incorrect assertion if you're applying that to TypeScript.

The same can be done to it that would be done to Flow: you can just either strip types manually, or just do a single export to your ECMAScripttarget of choice. It'll be native JavaScript. Even the little shims/polyfills it does (to support older ECMAScript versions if you wish to export to it) are optional and can be disabled.

TypeScript has `--target ESNext` this will strip out any TypeScript-specific type annotations, and leave you with standard-track-only JS code that looks identical to your input (modulo type annotations).
