=={{header|JavaScript}}==

See [[Named parameters#JavaScript]], to pass named parameters one uses an object with properties set:

<lang javascript>function sorter(table, options) {

opts = {}

opts.ordering = options.ordering || 'lexicographic';

opts.column = options.column || 0;

opts.reverse = options.reverse || false;

// ...

}

sorter(the_data, {reverse: true, ordering: 'numeric'});</lang>
