Enabling rich IDE support is precisely the point of TypeScript and similar enhancements like Python 3 type annotations: Give the computer in front of you enough information to automatically do for you what you would otherwise have to do manually, freeing you up to focus on higher level problems.
And at the same time doing what Java did, abstracting away what is under the hood, so when something brakes. SOL. But this might be good, keep JS for the Pro's and TS for the Joe's?
