Yeah that list has left me wondering, then what is it good at? HTML, CSS and JavaScript?
SQL. I learned a lot using it. It's really good and uses teh full potential of Postgres. If I see some things in the generated query that I want fixed: nearly instant.
Also: it gives great feedback on my schema designs.
So far SQL it's best. (comparing to JS/ HTML+Tailwind / Kotlin)
It’s been amazing for me for Go and TypeScript; and pretty decent at Swift.
There is a steep learning curve. It requires good soft eng practices; have a clear plan and be sure have good docs and examples. Don’t give it an empty directory; have a scaffolding it can latch onto.
