const watcher = new Watcher()

const watch = watcher.add('a[href]', result => {
  console.group(`Added ${result.added.length} links, removed ${result.removed.length} links`)
  for (const a of result.added) {
    console.log(`Added: %o`, a)
  }
  for (const a of result.removed) {
    console.log(`Removed: %o`, a)
  }
  console.groupEnd()
})

watcher.start()
