Usage

SemVer.resolve(range: string, versions: Array<string>, preRelease: boolean?): string

var versions = [
  '1.0.1',
  '1.1.9',
  '1.0.0',
  '2.0.0',
  '0.1.1-alpha',
  '1.3.2',
  '0.2.3-pre',
  '0.2.4-pre',
  '0.2.0',
  '0.0.12',
  '0.0.13-pre'
];

// resolving a specific version
SemVer.resolve('1.1.9', versions) //=> '1.1.9'
// resolving a patch range
SemVer.resolve('~1.0.0', versions) //=> '1.0.1'
// resolving a minor range
SemVer.resolve('^1.0.0', versions) //=> '1.3.2'
// resolving the latest version
SemVer.resolve('latest', versions) //=> '2.0.1'
// allow pre-release resolution
SemVer.resolve('^0.1.0', versions, true) //=> '0.2.4-pre'
// deny pre-release resolution
SemVer.resolve('^0.1.0', versions, false) //=> '0.2.0'
