Generate a new array, specifying its type, and populate it by utilizing Angular

My current situation involves a variable that is an array with the type Club. Within this array, a function is responsible for populating it.

clubs: [Club];

This function is as follows:

this.authService.getAllClubs().subscribe(
      clubs => {
        var result = [];

        if(clubs.length > 0) {
          for (const club of clubs) {
            let c = club.club;
            let b = new Club(c.id, c.name, false);
            result.push(b);
          }
        }
         this.clubs = result;

      }
    );

An issue arises when running this code: (this.clubs = result;)

Property '0' is missing in type 'any[]' but required in type '[Club]'.ts(2741)

How can I correctly create an array with the type club? What steps should be taken to rectify this error?

Answer №1

It appears there may be some confusion between two distinct types:

[Car]: represents a single Car within a tuple

Car[]: signifies an array containing multiple Car elements

Be sure to input the correct type and adjust accordingly to ensure proper functionality
