Although I write the necessary codes, I can't get results [closed]

Question

Laptop text and price should appear on the blue button. Although I write the necessary codes, I can't get results

  <div class="card" style="width: 18rem;" >
  <img src="https://picsum.photos/400" class="card-img-top" alt="Card image cap"/>
  <div class="card-body" >
    <h5 class="card-title">
      {{product.name}} {{product.price | currency:'USD':true:"1.2-2"}}</h5>
        <p class="card-text">
          {{product.description}}
        </p>
    <a href="#" class="btn btn-primary">Go Somewhere</a>
  </div>

and product.price I get an error no code errors, can't see in browser

It should have written where I marked what the above code requires

.ts code

  export class Product{
  id:number;
  name: string;
  price:number;
  categoryId:number;
  description:string;
  imageUrl:string;
}

Things you should check:

• Do the <h5> <p> tags exist in the inspector (browser development tools)?
• Are you sure the css doesn't hide the elements for some reason? e.g. Change the line {{product.name}} {{product.price | currency:'USD':true:"1.2-2"}}</h5> to {{product.name}} {{product.price | currency:'USD':true:"1.2-2"}}TEST</h5> - Does TEST show up? if yes, css should be fine
• If the above points are ok, I suspect that product or product.name/product.currency are undefined. Maybe add a this.product.name='test'; in your component to make sure it has a value
