sort an array of strings in ascending alphabetical order in JavaScript ES6

// Recursivly sort strings ascending alphabetically
// length takes priority over alphabetic order
function sortAlphaAsc (arrayOfStrings) {
  function alphaAsc(a, b, index) {
    if (a.length < b.length) return -1;
    if (a.length > b.length) return 1;
    return (index !== a.length) ? ((a.charAt(index).toLowerCase() === b.charAt(index).toLowerCase()) ? alphaAsc(a, b, index + 1) : ((a.charAt(index).toLowerCase() < b.charAt(index).toLowerCase()) ? -1 : 1)) : 0; // () for readability
  }
  return arrayOfStrings.sort((c, d) => alphaAsc(c, d, 0))
}

let array =          
   ["","j","u","ju","m","jm","um","jum","p","jp","up","jup","mp","jmp","ump","jump"]; 
let arrayCopy = [...array];
console.log(sortAlpha(array)); 
// ["","j","m","p","u","jm","jp","ju","mp","um","up","jmp","jum","jup","ump","jump"]
// Compared to regular alphabetical sort.
console.log(arrayCopy.sort((a,b) =>  a.localeCompare(b)));
// ["","j","jm","jmp","jp","ju","jum","jump","jup","m","mp","p","u","um","ump","up"]

Ex: Use for formatting power sets with sorted characters =>

rawPowerSet = ["", "j", "m", "p", "u", "jm", "jp", "ju", "mp", "um", "up", "jmp", "jum", "jup", "ump", "jump"]

sortedPowerSet = sortAlphaAsc(rawPowerSet.map((string) => sortAlphaAsc(string.split('')).join('')))

// ['', 'j', 'm', 'p', 'u', 'jm', 'jp', 'ju', 'mp', 'mu', 'pu', 'jmp', 'jmu', 'jpu', 'mpu', 'jmpu']
