What is the best method for thoroughly searching through an object's contents?

Exploring the world of TypeScript and seeking assistance with a query.

I currently have an object structured as follows:

    public storeID: number,
    public storeName: string,
    public storeBio: string,
    public storeCoverImage: string,
    public storeLogo: string,
    public storeGallery: string[],
    public storeIsFeatured: boolean,
    public storeAmenities: string[],
    public storeContactInfo: {
      // Contact information details here...
    },
    public storeConfig: {
      allowRemoteSignup: boolean;
    },
    public userSuscriptions: [
      {
        userID: number;
        availableCredit: number;
        discounts: [
          {
            globalDiscount: number;
            itemDiscount: [
              {
                itemID: number;
                itemPrice: number;
              }
            ];
          }
        ];
      }
    ],
    public menuNotificationSuscriptions: number[],
    public eventNotificationSuscriptions: number[]

My goal is to obtain a result where userSuscriptions.userID = 3 (which may include multiple entries).

I've attempted nested filters but haven't achieved success. Any suggestions or solutions are appreciated!

Answer №1

There are several ways to approach this problem, and the most suitable method will depend on the structure of your data and the desired output format.

One option is to use nested filters. The inner filter checks for a specific ID value (in this case, 3) within each user's subscriptions, while the outer filter collects all users that meet this criteria.

This approach can also be applied to search for multiple IDs within the inner object.

const result = this.data.filter(u => u.userSubscriptions.filter(s => s.userID === 3).length > 0);

Alternatively, you can utilize array.find() if you only want to retrieve one user with a particular ID.

const result2 = this.data.find(u=> u.userSubscriptions.find(s=> s.userId === 3) !== undefined);

Lastly, make sure to double-check your spelling, as "Suscriptions" should be spelled as "Subscriptions".
