Change from String to Array using .split(), then sort

string.split()

//Create a variable with a string separated by commas
var friends = "Moe,Larry,Curly,Jane,Emma,Elizabeth,Elinor,Mary,Darcy,Grey,Lydia,Harriet";

//Create a new array of the string using the .split() method
//The split method needs the separator such as a comma or space ==> str.split([separator[, limit]])
var newFriends = friends.split([',']);
console.log(newFriends);

//Sort the new array
newFriends.sort();

//==> [ 'Curly',
  'Darcy',
  'Elinor',
  'Elizabeth',
  'Emma',
  'Grey',
  'Harriet',
  'Jane',
  'Larry',
  'Lydia',
  'Mary',
  'Moe' ]
