If a fix only works on your laptop, it is not a fix. It is a temporary illusion.
A lot of bugs survive because we test in the exact environment where we built the feature. Same browser, same cached data, same .env, same DB shape, same user role.
Then it goes to staging or production and breaks immediately.
Real habit to build:
Before marking anything “done”, test at least these:
- fresh login
- different role or permission
- empty state
- bad input
- mobile view
- slow network or failed API case
Most production issues do not come from complex logic.
They come from untested assumptions.

Stop Using map() for Side Effects
Using Array.map() for side effects leads to confusing code and unnecessary memory usage.
💡Don’t Hide Errors Behind Generic Toasts
A “Something went wrong” message helps nobody. Log the real error and show users what they can do next.
💡Always Add Timeouts to External API Calls
Never call external APIs without a timeout — one slow dependency can freeze your entire system.
