var names = ['name', 'name', 'othername', 'name', 'othername'];
names.forEach(function(name) {
  console.log( nodupes(name) );
});

Output:

$ node example/nodupes.js

Usage

var nodupes = require('nodupes');

var nd = nodupes(options)

Call nodupes() to get a new nodupes function, with its own index and options.

Options:

var options = {
  names: {},           // Load a pre-existing names index (see `nd.getNames()`).
  suffixFirst: false,  // Add a suffix on the first appearance of a name.
  separator: '-'       // Change the suffix separator.
};

nd('name')

Returns the name with an appended suffix if needed.
