}, {
firstname: 'Kobe',
secondname: 'Bryant'
}, {
firstname: 'Shaquille',
secondname: 'O\'Neal'
}, {
firstname: 'Magic',
secondname: 'Johnson'
}];
// Filtering students whose firstname comes before secondname.
var testStudents = _.filter(students, function(student){
return student.firstname < student.secondname;
});
// Sorting the array in ascending order.
testStudents = _.sortBy(testStudents, function(student){
return student.firstname + ' ' + student.secondname;
});
// Reversing the array.
testStudents = testStudents.reverse();
// Displaying the result.
console.log(testStudents);
