Way 1: Convert your interface to a class

export class Category {
  name: string;
  description: string;
}
const category: Category = new Category();

Way 2: Extend your interface as a class

 export class CategoryObject implements Category { }
const category: Category = new CategoryObject();

Way 3: Fully specify your object, matching the interface

const category: Category = {
  name: 'My Category',
  description: 'My Description',
};

Way 4: Make the properties optional

export interface Category {
  name?: string;
  description?: string;
}

const category: Category = {};

Way 5: Change your variable's type to use Partial<T>

export interface Category {
  name: string;
  description: string;
}

const category: Partial<Category> = {};
