Another way to develop would be through iterating within a Unit Test that you don't plan to keep around.
Uh, I set a breakpoint and run the app?
To add a bit more context, it's more difficult to configure a debugger when the application is running within something like Docker. How difficult? That depends on the language and tools you're using.
I know profilers and debuggers are a boon for productivity, but anecdotally I've found they're seldom used. How often do you use debuggers/profilers in your work? What's preventing you? conversely, what enables you to use them?
