Method plural

/**
 * Like Text::sprintf but tries to pluralise the string.
 *
 * Note that this method can take a mixed number of arguments as for the sprintf function.
 *
 * The last argument can take an array of options:
 *
 * array('jsSafe'=>boolean, 'interpretBackSlashes'=>boolean, 'script'=>boolean)
 *
 * where:
 *
 * jsSafe is a boolean to generate a javascript safe strings.
 * interpretBackSlashes is a boolean to interpret backslashes \\->\, \n->new line, \t->tabulation.
 * script is a boolean to indicate that the string will be push in the javascript language store.
 *
 * Examples:
 * `<script>alert(Joomla.Text._('<?php echo Text::plural("COM_PLUGINS_N_ITEMS_UNPUBLISHED", 1, array("script"=>true)); ?>'));</script>`
 * will generate an alert message containing '1 plugin successfully disabled'
 * `<?php echo Text::plural('COM_PLUGINS_N_ITEMS_UNPUBLISHED', 1); ?>` will generate a '1 plugin successfully disabled' string
 *
 * @param   string   $string  The format string.
 * @param   integer  $n       The number of items
 *
 * @return  string  The translated strings or the key if 'script' is true in the array of options
 *
 * @since   1.7.0
