const students = [
{ name: "Alice", score: 92 },
{ name: "Bob", score: 87 },
{ name: "Charlie", score: 95 },
{ name: "David", score: 78 },
{ name: "Emma", score: 90 },
];
const highScorers = students.___((___) => {
return ___;
});
for (let i = 0; i < highScorers.length; i += 1) {
console.log(highScorers[i].name);
}
