Are .d.ts files strictly for type implementations?

Question

Are typescript .d.ts files strictly for types? In other words no constants or actual function implementations should exist in these files?

[yes](https://basarat.gitbooks.io/typescript/docs/types/ambient/d.ts.html) — Rico Kahler, Apr 14 '17 at 01:30
`d.ts` files are only for types. Actual constants and function implementations will be inside your `js` file if types are for your JavaScript code. — Hardik Modha, Apr 14 '17 at 01:32

Yes. *.d.ts files are places to hold ambient declarations. i.e. type definition without actual code that describes the runtime environment.
