Old Norse Alphabet Sort

Sort arrays by Old Norse alphabet in Node.js.

Usually localeCompare() or Intl.Collator() is enough to get alphabetical order, but there are edge cases like Icelandic and Old Norse alphabets. LocaleCompare seems to have hard time properly telling apart letters like a, æ or á. This package provides custom sorter for getting old norse alphabetical order just right.

Depends on Old Norse Alphabet package.

Install

yarn add old-norse-alphabet-sort

const { oldNorseSort } = require('old-norse-alphabet-sort')

const words = ['öðli', 'ógnan', 'æðrask', 'aðili', 'þakkan', 'áfir', 'él-ligr', 'ef-lauss', 'œgir', 'maðr']

const sortedWords = [...words].sort((a, b) => oldNorseSort(a, b))
// ['aðili', 'áfir', 'ef-lauss', 'él-ligr', 'maðr', 'ógnan', 'þakkan', 'æðrask', 'œgir', 'öðli']

With arrays of objects:

const { oldNorseSort } = require('old-norse-alphabet-sort')

const words = [
  {
    word: 'æðrask',
    definitions: [...]
  },
  {
    word: 'af-burðr',
    definitions: [...],
  }
]

const sortedWords = [...words].sort((a, b) => oldNorseSort(a.word, b.word))
