Handle promise result

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

The same task, four prompts

A promise returns data we need to render. Add a .then handler that extracts response.data, update state with the value, add a .catch that logs a clear error with context, and ensure a loading flag is set false in both success and failure paths.

Before I change the component to use the promise result, make the flow easy to review. Show where to extract response.data, how to update setState safely if the component might unmount, and provide an error message that tells a reviewer whether this failure is recoverable or not.

The promise resolves but I still see empty UI
I added a .then to call setItems(response.data) but the list stays empty. I suspect the response shape is wrong or setState runs after unmount. I don't know which. How do I quickly tell whether response.data is empty versus setState being ignored and what minimal change unblocks the UI now?

We repeatedly mishandle async results and leak state updates
Across projects we keep getting race conditions: components update state after unmount or assume promise shapes. I want a practical rule to avoid these bugs. Recommend one pattern for handling promises in components, one test to add to our suite to catch stale updates, and a brief PR lint item reviewers should check.

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from JavaScript's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
