My post was directed at back-end development in Typescript/Javascript. My apologies if that wasn't clearer. I don't really have any experience in front-end development in Typescript, so I can't really comment on that. It could be a real improvement there for all I know.

While your parent clarifies that he meant for backend- ill suggest trying one off bucklescript, Scala.js or elm. They are all very well done and have wide adoption actually
