function makeIndent(indentLength) {
  return ".".repeat(indentLength);
}

function logItems(bookmarkItem, indent) {
  if (bookmarkItem.url) {
    console.log(makeIndent(indent) + bookmarkItem.url);
  } else {
    console.log(makeIndent(indent) + "Folder");
    indent++;
  }
  if (bookmarkItem.children) {
    for (child of bookmarkItem.children) {
      logItems(child, indent);
    }
  }
  indent--;
}

function logTree(bookmarkItems) {
  logItems(bookmarkItems[0], 0);
}

function onRejected(error) {
  console.log(`An error: ${error}`);
}

var gettingTree = browser.bookmarks.getTree();
gettingTree.then(logTree, onRejected);
