The tooling for Typescript still isn't good enough to claim that accolade. There are still combinations of libraries, linters, editors, and frameworks, that throw opaque errors that will roadblock students and junior developers significantly. Ultimately until browsers can accept Typescript directly without a compilation step it will remain a second-class citizen. Until then, all of Webpack, gulp, parcelJS, problems and inefficiencies are Typescript's problems and inefficiencies.

It's not fair - Microsoft and co. have done a tremendous job with the implementation and documentation of Typescript. But the reality exists nonetheless.
