Analyze data with JavaScript

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.

Write a script to parse the CSV file of monthly sales data, calculate the total revenue for each product category, and display it in a table on the sales analytics page for the finance team.

Before I present this sales data analysis to the finance director, make it more insightful. It needs to highlight the top 3 performing product categories, flag any categories with a month-over-month revenue decrease, and allow filtering by region, because they need to make quick strategic decisions for next quarter.

The sales data analysis is showing incorrect totals for some categories, and the finance team just flagged it.
The sales data analysis I just pushed to the dashboard is showing incorrect revenue totals for the 'Electronics' and 'Apparel' categories, and the finance team just flagged it, right before their budget meeting. I'm not sure if it's a parsing error with the CSV, an issue with my aggregation logic, or a data type mismatch. The finance director needs accurate numbers by Friday. What's the most likely source of this data discrepancy, and what's the quickest way to verify and correct the calculations?

I consistently struggle to present complex data clearly and concisely to non-technical stakeholders.
I consistently struggle to present complex data analysis to non-technical stakeholders like the marketing and sales teams in a way that's clear, concise, and actionable. They often get lost in the details or miss the key takeaways, leading to follow-up meetings and confusion. What habit should I change to ensure my data visualizations and summaries are always tailored to their decision-making needs, especially when I'm reporting on critical business metrics?

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.
