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