Sort array by firstname (alphabetically) in Javascript

Question

I got an array (see below for one object in the array) that I need to sort by firstname using JavaScript. How can I do it?

var user = {
   bio: null,
   emai

I'm surprised no one mentioned Collators. You shouldn't use localeCompare unless you have to as it has significantly worse performance.

const collator = new Intl.Collator('zh-CN', { // Chinese Simplified for example
  numeric: true,
  sensitivity: 'base',
});

function sortAsc(a, b) {
  if (typeof a === 'string' && typeof b === 'string') {
    return collator.compare(b, a)
  }

  return b - a;
}

function sortDesc(a, b) {
  if (typeof a === 'string' && typeof b === 'string') {
    return collator.compare(a, b);
  }

  return a - b;
}
