withNumbersDescending

(left: number, right: number) => number

A compare function which orders numbers from largest to smallest.

Try It

const nums = [2, 3, 1]
const updatedNums = nums.toSorted(withNumbersDescending)
console.log(updatedNums) // is [3, 2, 1]
const nums = [2, 3, 1]
const updatedNums = nums.toSorted(withNumbersDescending)
console.log(updatedNums) // is [3, 2, 1]

Try It

const nums = [2, 3, 1]
const updatedNums = nums.toSorted(
  withNumbersDescending
)
console.log(updatedNums) // is [3, 2, 1]
const nums = [2, 3, 1]
const updatedNums = nums.toSorted(
  withNumbersDescending
)
console.log(updatedNums) // is [3, 2, 1]

We often need to order numerically. Below, we have baseball's home run leaders. Let's see who has the most home runs.

Try It

const players = [
  {
    name: 'Shohei Ohtani',
    homeRuns: 38,
    strikeouts: 125,
  },
  {
    name: 'Cal Raleigh',
    homeRuns: 41,
    strikeouts: 116,
  },
  {
    name: 'Aaron Judge',
    homeRuns: 37,
    strikeouts: 120,
  },
]

const byHomeRunsDesc = compareByProp('homeRuns', withNumbersDescending)
const orderPlayers = order(byHomeRunsDesc)
const updatedPlayers = orderPlayers(players)
console.log(updatedPlayers)
// is [
//   {
//     name: Cal Raleigh
//     homeRuns: 41
//     strikeouts: 116
//   }
//   {
//     name: Shohei Ohtani
//     homeRuns: 38
//     strikeouts: 125
//   }
//   {
//     name: Aaron Judge
//     homeRuns: 37
//     strikeouts: 120

// ]
type Player = {
  name: string
  homeRuns: number
  strikeouts: number
}

const players: Player[] = [

const byHomeRunsDesc = compareByProp('homeRuns', withNumbersDescending)<Player>
const orderPlayers = order(byHomeRunsDesc)
const updatedPlayers = orderPlayers(players)
console.log(updatedPlayers)
