problem on debugging simple code test with IDE

 The support for Kotlin is far worse than Java and C# on VSCode.  The only thing I could get working was 'Code Runner' and Run/Debug with gradle project.

- Debugger for single file

This made the experience of using kotlin for leetcode far worse than Java or Python from within the VSCode IDE.

Support for Kotlin on Intellij is better.  Single file can be debugged.  

The leetcode extension on VSCode is what I miss, however.  Since the popularity of VSCode surged, the number and quality of extensions on Idea is simply outmatched.

The issue also exists on Typescript development.  While writing code test, I wished to use some type hint for better auto completion support but not wishing to get into the trouble of building and compiling.  Directly using debugger for single file ts is also not easy on VSCode and Intellij.
