Use through instead of map when using pagination

When you want to map paginated data and return only a subset of the fields, use through rather than map. The map breaks the pagination object and changes it's identity. While, through works on the paginated data itself

 1// Don't: Mapping paginated data
 2$employees = Employee::paginate(10)->map(fn ($employee) => [
 3    'id' => $employee->id,
 4    'name' => $employee->name
 5])
 6 
 7// Do: Mapping paginated data
 8$employees = Employee::paginate(10)->through(fn ($employee) => [
 9    'id' => $employee->id,
10    'name' => $employee->name
11])
