Simple example:
const strings = ['Flowers', 'Pots', 'Soil'];
const listItems = strings.map(string => <li>{string}</li>); 
<ul>{listItems}</ul>

Another example:
export default function App() {
const elements = data.map(item => {
  return <Card img={item.img} info={item.info} /> 
})
return (
  <div>
    {elements}
  </div>
  )
}

function Card(props) {
const professors = [
    {id: 1, subject: "math", name: "Roberts"}, 
    {id: 2, subject: "english", name: "Tucker"},
    {id: 2, subject: "math", name: "Smith"},
    {id: 2, subject: "english", name: "Tucker"},
    {id: 2, subject: "math", name: "Marks"},
    {id: 2, subject: "math", name: "James"}
  ];
const mathTeachers = professors.filter(teacher => teacher.subject === 'math'); 

const list = mathTeachers.map(teacher => 
  <div>
    <h2> {teacher.name} </h2>
    <p> {teacher.contactInfo} </p>
  </div>
);

return (
    <div>{list}</div>
  )
};

const list = jobs.map((job, i) =>
  <li key={'job-' + i}>{job}</li>
);

export default function App() {
const cards = data.map(item => {
return (
  <Card
    key={item.id}
    img={item.coverImg}
    rating={item.stats.rating}
    reviewCount={item.stats.reviewCount}
    location={item.location}
    title={item.title}
    price={item.price}
    />
  )
});

return (
  <div>
    {cards}
  </div>
  )
}
