var list = new LinkedList()

for (var i = 0; i < 10; i++) {
  list.push(i.toString())
}

console.log(list.head)
console.log(list.tail)

while (list.next()) {
  console.log(list.current)
}

while (list.length) {
  console.log(list.pop())
}

for (i = 0; i < 10; i++) {
  list.unshift(i.toString())
}

while (list.length) {
  console.log(list.shift())
}

for (i = 0; i < 10; i++) {
  list.push(i.toString())
}

while (list.next()) {
  if (list.current === '5') {
    console.log('move "%s" to the start of the list', list.unshiftCurrent())
  }
  if (list.current === '8') {
    console.log('remove "%s" current from the list', list.removeCurrent())
    // now list.current points to '7'
    // now list.next() points to '9'

    list.resetCursor()
    // now list.next() points to list.head
  }
}
