Personally I've moved away from the TypeScript compiler and towards the betas of `babel@7` and `@babel/preset-typescript` (https://www.npmjs.com/package/@babel/preset-typescript). It seems to be faster and there is better integration with `jest`, `rollup`, various css-in-js libraries and (maybe in future?) `create-react-app`. (I still run `tslint` and `typescript` in the background for type-checking and linting. And I've written a tiny CLI to generate flat `index.d.ts` files to share my packages.) The one thing I still miss about JavaScript is the possibility of writing codemods to speed-up upgrades. Unfortunately, in order for `jscodeshift` to support TypeScript, I think there would need to be some further work on `recast` (https://github.com/benjamn/recast/issues/424). Hopefully the TypeScript team will continue to work closely with the

Babel team, since this would be very good for the eco-system.
