Property

By defining an items property, this will supply a default behavior for items in the list.

Setting the wildcard is useful when items should be converted to a particular type.

import { ObservableArray, ObservableObject, type } from "can/everything";

class Person extends ObservableObject { /* ... */ }
class People extends ObservableArray {
  static items = type.convert(Person);
}

let scientists = new People([
  { first: "Ada", last: "Lovelace" },
  { first: "John", last: "McCarthy" }
]);

console.log(scientists[0] instanceof Person);
// -> true
