Usage

Fuzzy Pop is super simple. You give it an input string and an array of values, and it'll give you back the matching items, sorted by popularity.

var fp = require('fuzzy-pop'),
  array = [{
    value: 'foo',
    count: 30,
    latest: new Date('2015-01-02')
  }, {
    value: 'bar',
    count: 100,
    latest: new Date('2015-01-01')
  }, {
    value: 'foobar',
    count: 50,
    latest: new Date('2015-05-01')
  }, {
    value: 'foobarbaz',
    count: 10,
    latest: new Date('2015-05-02')
  }];

fp('foo', array);

/* returns:
  [ { value: 'foobar',
      count: 50,
      latest: Thu Apr 30 2015 20:00:00 GMT-0400 (EDT),
      score: 0.008991589643452504 },
    { value: 'foobarbaz',
      count: 10,
      latest: Fri May 01 2015 20:00:00 GMT-0400 (EDT),
      score: 0.0024766818556312426 },
    { value: 'foo',
      count: 30,
      latest: Thu Jan 01 2015 19:00:00 GMT-0500 (EST),
      score: 0.00001622207651379491 } ]

  note: 'bar' isn't returned because it doesn't match! (⌐■_■)

It uses HackerNews's algorithm and only deals with counts, so the decay is really basic.
