Simple .sortBy implementation for JS

index.js

function compare(x, y) {
  return x > y
}

/**
 * @param {any[]} array list of items
 * @param {() => boolean} f function selector
 */
function sortBy(array, f) {
  return array.sort((x, y) => compare(f(x), f(y)))
}

export const SomeEnum = {
  CRITICAL: 'CRITICAL',
  CONTINUE: 'CONTINUE',
  READY: 'READY',
  order: item => {
    return Object.values(PlanToothStatus).findIndex(value => value === item)
  },
}

const result = sortBy(Object.values(SomeEnum), element => SomeEnum.order(element))
// Output will be
// ['CRITICAL', 'CONTINUE', 'READY', [function: order]]
