Typescript is one of the few additional layers of complexity that I truly feel is usually worth it. The exceptions being: a) if you have a complete or near-complete system that functions as intended with no major changes planned for the foreseeable future. And b) the system you’re writing is small, fairly self-contained, and the team isn’t already familiar with Typescript. In any other situation I firmly believe the benefits Typescript brings very quickly outweigh the small amount of added complexity.
