I'm hesitant to work in any JavaScript code base that isn't using TypeScript at this point. Two years ago, it was painful to use as any early release is but the benefits were obvious.
My biggest wish for TypeScript is that it was easier to use experimental flavors that supported JS features currently being considered, such as the pipeline operator proposal.
