function searchQuery (query) {
var queryResults = query ? $scope.fullList.filter(applyFilter(query)) : [];
return queryResults;
}
Can someone explain the purpose of the question mark ? in this function? Is it indicating optionality?
Essentially, if the value of query is considered true (
typeof query != 'undefined' && query != null && query != 0 && query != false$scope.allContacts.filter(createFilterFor(query))[]) will be returned.
This approach ensures that an array will always be returned in any case.
If a check for query ? is omitted and query happens to be null, there is a risk of encountering errors when running
