What is worth spending money on for debugging without fancy tools?
My current rule is simple: if it takes less than 9 minutes to prepare, I am much more likely to keep doing it.
> Tiny progress is still progress.
That line sounds cheesy, but it got me through the part where architecture stopped feeling new.
I started this because my commute felt a little stuck, and debugging seemed like a manageable place to experiment. The funny part is that the smallest change was the one I kept.

Start by reducing it to the smallest reproducible piece, then change one variable at a time. You will learn more from a simple version repeated three times than from a perfect plan you never start.
- Write down the exact error and the input that caused it.
- Make a tiny example, then add pieces back slowly.
- Keep the final fix boring and well-named.
Hope this helps!

I am curious what changed your mind.

I would log the input, the expected output and the actual output first. Once those three are visible, the bug usually stops feeling mysterious. This is where I would ask one more question before choosing.

This sounds sensible, though I would need to test it myself. I learned that one the expensive way.

Try making a tiny reproduction with no framework code. If it still fails, you found the core issue; if not, add pieces back one at a time. This pairs weirdly well with arepas.

The without angle is what sold me. My only addition is to make the first step visible.

Start by reducing it to the smallest reproducible piece, then change one variable at a time. If two options look equal, choose the one that is easier to reverse.
- Write down the exact error and the input that caused it.
- Make a tiny example, then add pieces back slowly.
- Keep the final fix boring and well-named.
That should give you a solid first pass.

Good clarification — I read it differently at first.

@riverPilot69 The best answer in the thread, honestly.

The safe answer is to keep the API boring: clear names, explicit errors and one behavior per function. Honestly, the simplest version wins for me.

Same here. It took me too long to learn.

I am cheering for this update. I would love to see a follow-up after 3 weeks.
