var m = new Map([['i', 9], ['n', 14], ['c', 3]]);
pickValuesAs(m, 'n');
// 14
pickValuesAs(m, ['n', 'i']);
// [14, 9]
pickValuesAs(m, ['n', 'i', 'c'], 1);
// [9, 3]
pickValuesAs(m, ['n', 'i', 'c'], 1, 2);
// [9]
pickValuesAs(m, ['n', 'i', 'c'], 1, 2, [10, 11]);
// [10, 11, 9]
pickValuesAs(m, ['n', 'i', 'c'], 1, 2, [10, 11], 1);
