A lightweight utility to determine the dxcc entity information from a callsign's prefix

This is my second NPM package, and I'm relatively new to Javascript. As I learn, breaking changes are not only possible, but likely. If you have feedback, I would love to hear it.

npm install dxccjs

Using the included file in ./data/cty.xml (current as of July 10, 2018, courtesy of ClubLog), you can instantiate a new instance of dxccjs and check a callsign as follows.

let dxcc = new dxccjs('./data/cty.xml')

asdf.on('loaded', () => {
  console.log( dxcc.checkCall('LU1EEP') )
})

Since it may take some time to parse the XML file, the loaded event is triggered when it has finished loading. Checking a call will result in the following object being returned:

{ '$': { record: '1722' },
  call: [ 'LU' ],
  entity: [ 'ARGENTINA' ],
  adif: [ '100' ],
  cqz: [ '13' ],
  cont: [ 'SA' ],
  long: [ '-58.4' ],
  lat: [ '-34.6' ] }

If a matching prefix is not found, { } is returned.

Tests are coming soon.

This is my second npm module. Send me PRs or comments. I'm here to learn!
