genderGuess.js

genderGuess tries to guess the gender of Icelandic names.

How it works

Checking a single name:

//When checking a single name you call genderGuess with a string, like so:

genderGuess('Óli Tómas Freysson');
// This specific example returns ---> 'male'

// The function will return one of these strings: 'male', 'female' or 'unknown' (lowercase)

Checking a list of names (array):

// When you call genderGuess with an array it will analyze the list

// The first parameter is the list of names (array)
// The second parameter is optional. If set then the results will also contain the names sorted into 3 lists (males, females and unknown)

//Example:

var people = ['Guðrún Arnardóttir', 'Björgvin Halldórsson', 'Bubbi Morthens', 'Jón Arnar Magnússon', 'Vala Flosadóttir'];

genderGuess(people); // This returns:
{
  "males": 2,
  "females": 2,
  "unknown": 1
}

// genderGuess can also be called with the second parameter (argument) as true:
genderGuess(people, true); // This returns:
{
  "males": 2,
  "females": 2,
  "unknown": 1,
  "lists": {
    "unknown": ["Bubbi Morthens"],
    "females": ["Guðrún Arnardóttir", "Vala Flosadóttir"],
    "males": ["Björgvin Halldórsson", "Jón Arnar Magnússon"]
  }
}

It is worth pointing it out that this script is extremely light and is kind of useless if you dont have full names (for now at least). I work at an advertising agency and we just ran a campaign and collected over 8000 names. This script was able to analyze 89% of those names. Pull request and ideas for improvement would be awesome!
