How to use JavaScript to sort an array of objects by a specific key like price?

Love both of these takes. In fact, I ran into this a lot while working on dynamic data tables in dashboards. So if you want more flexibility—like sorting by price, zipCode, or any other field—you can wrap this into a reusable function:

function sortByKey(array, key, direction = 'asc') {
  return array.sort((a, b) => {
    const valA = parseFloat(a[key]);
    const valB = parseFloat(b[key]);
    return direction === 'asc' ? valA - valB : valB - valA;
  });
}

Now you’ve got a plug-and-play way to javascript sort array of objects by key—any key, any direction. I usually pair this with dropdown filters or sortable column headers to make sorting super dynamic and user-friendly.
