Small algorithm for getting a list of latest versions from a version history.

getLatestVersion

var g = [
  {
    v: '1.0.0',
    f: ['README.md', 'new/images/image1.jpg','new/images/image2.jpg','new/images/image3.jpg']
  },
  {
    v: '0.2.0',
    f: ['README.md', 'foo/bar/bar.txt']
  },
  {
    v: '0.1.0',
    f: ['README.md', 'foo/bar/bar.txt','foo/foo.txt']
  }
];


var files = {};
g.forEach(function(version) {
  version.f.forEach(function(file) {
    if (!files[file]) {
      files[file] = version.v;
    }
  });
});

console.log(files);
