Is it necessary for the object name to begin with a lowercase letter?

Question

Is it necessary for the object name to begin with a lowercase letter?

export class Dish { 
}

File2

import { Dish } from '../shared/dish';
const DISHES: Dish[] = [
  {
    id: '0',
    name: 'Uthappizza',
    image: '/assets/images/uthappizza.png',
    category: 'mains',
    featured: true,
    label: 'Hot',
    price: '4.99',
}
]
export class MenuComponent implements OnInit {
  dishes: Dish[] = DISHES;
}

Can you explain why the properties are accessed using dish.name and dish.image instead of Dish.name, given that the array is named Dish[] and the class is named Dish?

Answer №1

Because the term "Dish" is being used to represent a category or type, not a specific value.

If you wish to utilize the Dist class itself, it must be defined within the current component. From there, you will only have access to its static classes, like so:

export class Dish {
    static a: 10;
}

export class B {
    Dish = Dish; // Assigning the static variable Dish to the property Dish of class B (with the same name)
}

Then, within the component implemented by class B, you can reference this in the template as follows:

<div>{{ Dish.a }}</div>
<!-- This will display 10 -->
