JavaScript Sort algorithm

sortArrayOfObjects.js

const data = [
  { first: 'David', last: 'Goldstein', age: 92 },
  { first: 'Tom', last: 'Stamper', age: 23 },
  { first: 'Sally', last: 'Brunswick', age: 76 },

// localeCompare is a String prototype:
// template literals are used to convert Numbers to Strings rather than `String()` or `'' + num`
// due to performance on large collections
// `String.toString()` is not used because it doesn't handle falsy values
// falsy values should really be trimmed, but they are not in this gist

const sort = ({ data, field, desc }) => {
  if (desc) {
    return data.sort((a, b) => `${b[field]}`.localeCompare(`${a[field]}`))
  }

  // if desc is omitted, we will sort by ascending
  return data.sort((a, b) => `${a[field]}`.localeCompare(`${b[field]}`))
}

console.log(
  sort({ data, field: 'age', desc: true })
);
