.map() function in JS used on a CONST variable

const listItems = products.map(product =>
  <li key={product.id}>
    {product.title}
  </li>
);

const listItems = products.map(product =>
  <li key={product.id}>
    {product.title}
  </li>
);

const listItems = products.map(product =>
  <li key={product.id}>
    {product.title}
  </li>
);

const listItems = products.map(product =>
  <li key={product.id}>
    {product.title}
  </li>
);

How can listItems be a const? The array elements are appended as we loop through ? Can someone explain what is happening here please.
