var FrequencyList = require('frequency-list'),
    list = new FrequencyList;
    .add('how are you')
    .add('whats up')
list.has('how are you') // true 
list.size('hi') // 2 
list.size('oh no') // 0 
list.unique('hi') // true 
$ component install matthewmueller/frequency-list

Initialize the FrequencyList with an optional array of values

Add a word or phrase to the frequency list

list.values(); //=> { 'hi' : 2, 'how are you' : 1, 'whats up' : 1 }
