Prompt examples and use cases
A well-structured prompt leverages the assistant’s strength. Here are three concrete examples.
// Prompt for Copilot X or Gemini Code
// Create a React component called "DataTable" that accepts props: rows (array), columns (array), onRowClick (function). Show a loading message while fetching data.
function DataTable({ rows, columns, onRowClick }) {
const [loading, setLoading] = useState(true);
const [data, setData] = useState([]);
useEffect(() => {
async function fetchData() {
setLoading(true);
const result = await fetch('/api/data')
.then(res => res.json())
.finally(() => setLoading(false));
setData(result);
}
fetchData();
}, []);
if (loading) return <p>Loading...</p>;
return (
<table>
<thead>
{columns.map(col => <th key={col}>{col}</th>)}
</thead>
<tbody>
{data.map(row => (
