I have this query where I have to pass a list and say if it exists. The question is for the use of IN in the bus, does it have to go in front or behind? If it is behind, why?

boolean existsByUserAndBusInAndCar(String User, List<String> bus, Car car);

I need to reuse a function across components that makes a call to multiple services. So my idea was to create a service which in turn calls the other services.

Component

  this.resul = this.escribirService.escribir(param1,param2);
  console.log(this.resul);

this is the service

 public escribir(
    param1: number,
    param2: string,
  ): boolean {

   let resultadoFinal:boolean = false;

    this.subscriptions.push(
   
      this.servicioL
        .getinfo1(param1, param2
        )
        .subscribe((resul1) => {
        resultadoFinal = resul1;
        
        }),

     
    this.servicioL
        .getinfo2(param1, param2    
        )
        .subscribe((resul2) => {
        resultadoFinal = resul2;
        
        }),
    return resultadoFinal;
  }

Clearly the return is incorrect and it always returns false since the return of the subscriptions arrive later. The question is, am I making a mistake creating a service to reuse this function? If it is correct to do this service, how do I make it synchronous and return the results of the subscriptions to the component? Thank you

The point is that I have this Array of objects.

(5) [{…}, {…}, {…}, {…}, {…}]
0: {id: 143, nombre: "1"}
1: {id: 208, nombre: "10"}
2: {id: 209, nombre: "Madrid"}
3: {id: 144, nombre: "Lugo"}
4: {id: 145, nombre: "3"}
5: {id: 152, nombre: "4"}

I need to order by the attribute, name that can be letters or numbers.

Try following examples like:

users.sort(function (a, b){
    return ( b.nombre.toLowerCase().localeCompare(a.nombre.toLowerCase()))
});

But it does not do it correctly, the result should be the following:

  (5) [{…}, {…}, {…}, {…}, {…}]
    0: {id: 143, nombre: "1"}
    1: {id: 208, nombre: "3"} 
    2: {id: 209, nombre: "4"} 
    3: {id: 144, nombre: "10"} 
    4: {id: 145, nombre: "Lugo"} 
    5: {id: 152, nombre: "Madrid"}

Any ideas?

Thank you

I am looking for a way in javascript to pass data from an object of one type to another of a different type.

The first object would be this

   (6) [{…}, {…}, {…}, {…}, {…}, {…}]
0:
date: "2018-03-29T13:34:00.000+0200"
location:
    locationx: "Almacen"
    id: 21
__proto__: Object
id: 7
__proto__: Object

Now I want to pass the locationx and date data to another object with this structure.

 pr: EventInput[] = [
    {
      title: '',  // Aquí seria locationx
      start: '',     // Aquí seria date
    },  
    {
      title: '',
      start: '',
    },
  ];

Keep in mind that there can be hundreds of data, any ideas? Thank you

EDIT

In FullCalendar I have to get the initial events from an http request.

export class AppComponent implements OnInit {

  constructor(
    private vacationService: VacationService,
  ) {}

  ngOnInit(): void {
    this.loadEvents();
  }

 pr: EventInput[] = [
    {
      title: 'All-day event',
      start: '2021-05-16',
    },
    {
      title: 'All-day event',
      start: '2021-05-18',
    },
  ];

  calendarOptions: CalendarOptions = {
    initialView: 'dayGridMonth',
    headerToolbar: { 
      left: '',
      center: 'title',
    },
    editable: true, 
    initialEvents: this.pr,  
  
  };

  loadEvents(): void {
      this.vacationService.getAll().subscribe((data) => {
        // My data
        console.log(data);
      })
  }
}

The pr variable contains the initial events that I can do manually but I need them to be from the data of my request to the database. In other words, I need to pass the data to the pr variable, taking into account that they have a different structure.
