Arguments
Certain hint options accept arguments. If the option is specified as a string, these arguments will be injected in place of $0, $1, etc. If the option is specified as a function, these will be the function arguments. Example:
new Calendar(calendarEl, {
  viewHint: function(buttonText, buttonName) {
    if (buttonName.match(/^dayGrid/)) { // matches "dayGridWeek"
      return buttonText + " list view" // results in "week list view"
    } else {
      return buttonText + " view" // results in "week view"
    }
  }
})
