Actually, modern IDEs are super helpful with JS and Python, especially with type hints.
I can export a function or class in a big JS project, go to any file, start typing the method name, and Webstorm will suggest the import. With JavaScript!
Not as great as the Java integration but still pretty nice.
I recently had to work on an unfamiliar JS codebase. After initially pulling my hair out trying to understand what objects were being passed where, I decided to define some types and parameters using JSDoc . VsCode picked them up instantly and it was like coding with a language server after that.
