I'm new to reactjs. I have an array of objects, I want this array to be global and be accessed from multiple components. How do I handle this? Do I create another class and then import it?

FYI in Angular I would've created a service containing this array to have access from all components.

carts = [
        {
            title: 'Travel',
            backgroundColor: '#796157',
            description: 'Keep your eyes fresh & travel to other countries.',
            image: hs1,
            gallery: [
                '/assets/images/capture_1_travel/4.jpg',
                '/assets/images/capture_1_travel/2.jpg',
                '/assets/images/capture_1_travel/3.PNG'
            ]
        },
        {
            title: 'Record',
            backgroundColor: '#8693A2',
            description: 'Record the most important moments.',
            image: hs2,
            gallery: [
                '/assets/images/capture_3_record/2.jpg',
                '/assets/images/capture_3_record/5.jpg',
                '/assets/images/capture_3_record/3.jpg',
                '/assets/images/capture_3_record/4.jpg',
                '/assets/images/capture_3_record/6.jpg'
            ]
        },
        ...
