> Transpiling is not a free operation, and comes with a lot of pros and cons. You could say the same for languages that require compilation, it's not exactly an uncommon pattern. JS will almost always have some kind of operation applied to it when running on the web (minification etc) so adding TypeScript transpilation is often a very small step. Is that ideal? No. But Python doesn't even run on the web, so of course it doesn't have these issues.
