Utilizing static variables within various components

My TypeScript file contains String arrays for services and surgeons:

export const servicesData =
    [
        'test',
        'test',
    ];

export const surgeonsData =
    [
        'test',
        'test',
    ];

In my application, I have multiple instances of a Component and I want to access these data-store arrays in a static manner so that all instances can use them without fetching them repeatedly.

Here's a summary of my current setup. Each booking component needs to utilize the arrays from the data-model.ts file without re-fetching them every time.

import { surgeonsData, servicesData } from 'app/data-models.ts'

@Component({
    selector: 'booking',
    template:
        `
          <div *ngFor="let s of surgeons">
            {{s}}
          </div>
        `
})


export default class BookingComponent {

    surgeons = surgeonsData;
    services = servicesData;

    constructor() {}


}

In the example above, each new component instance saves the surgeonData into the surgeon variable. Instead of this approach, I aim to create a single variable accessible to all components rather than duplicating it with each instance creation.

Utilize a service to utilize globally-accessible, constant variables. Attempting this without services may result in issues with Zoning and detection of changes.
