You could [define the entire type explicitly](https://www.typescriptlang.org/play?filetype=js#code/PQKhFgCgAIWgBALgTwA4FMAm6Bm0BK6AxogIYB2A5gDbpSwKoBOA9hkytAN7kCuAtgCN0TAL7QA7gEtMiABb048ZmxGceA4WOhNSiKS0WNW7dXyEjxAbTnoplOYgC6i4FFBKUGboRIUa6OIgbpAAbqRMOsRkVLTQALzQAPKCAFbRAHTYOFLk6AAKJmpS6ADOABRc9JIy8gBc0ACMAEwADK0ANNW6+iwNjQBs0MDQAJxQoh3c1bb2jg1VMNDLlOiI5QCU00vLy0xrvEzk0PJSpRnSsnLDJ3JnGT0GANzVy5Ov0KVr5eHUW4u7Xb7RCHY6nc6XeQJaC-Bjgh56Z4fUTVFGQUQbF6QKBEFjkUosWgZagsSjlfZ+WLoDKzByITFQIA): ```js /** * @typedef Rectangle * @property {number} width * @property {number} ratio * @property {number} [height] */ /** @type {Rectangle} */ var...

TypeScript supports reading types from JSDoc comments, which CoffeeScript already supports. I've been meaning to write a section in the docs explaining this; if anyone wants to beat me to...
