I see the component in react dev tools and each of the Summaries has a unique key on it. But the warning won’t go away.
const summaryData = [
{
id: 1,
box: "one",
sprite: "html5",
},
{
id: 2,
box: "two",
sprite: "envelope",
},
{
id: 3,
box: "three",
sprite: "wordpress",
},
{
id: 4,
box: "four",
sprite: "tongue",
},
];
{summaryData.map((summary) => (
<Summaries
key={`box${summary.id}`}
box={summary.box}
sprite={summary.sprite}
/>
))}
