Depending on what it is you're doing, I feel that .net and Java are far superior choices. Obviously these are pretty heavy languages, so obviously decide for yourself whether the size of your app justifies using a language like this. My thoughts run along the lines of: "If people are justifying using Typescript because their projects are large and critical, they're probably large and critical enough to use a language designed for enterprise-scale development." I personally haven't used Go, but I've heard good things about its use in this domain too.
