    Function every

    • Checks whether all items satisfy an async predicate. Short-circuits scheduling when the first false is found.

      Type Parameters

      • I

      Parameters

      • data: I[] | Promise<I[]>

        Input array, or a promise that resolves to one.

      • predicate: (item: I, token: CancellableToken) => Promise<boolean>

        Async predicate to evaluate.

      • Optionaloptions: EveryOptions

        Configuration options including cancellation and concurrency.

      Returns CancellableHandle<boolean>

      A cancellable handle resolving to true if all items match.

      const handle = every(
        [2, 4, 6],
        async (item, token) => {
          await token.sleep(5);
          return item % 2 === 0;
        },
        { concurrency: 2 },
      );

      const allEven = await handle; // true

      const handle = every(
        { a: 2, b: 4, c: 6 },
        async (value, key) => key !== "x" && value % 2 === 0,
      );

      const allMatch = await handle; // true

      Parameters

      • data: CollectionInput<I> | Promise<CollectionInput<I>>

      • predicate: (item: I, key: string | number, token: CancellableToken) => Promise<boolean>

        Async predicate to evaluate.

      • Optionaloptions: EveryOptions

        Configuration options including cancellation and concurrency.

      Returns CancellableHandle<boolean>

          return item % 2 === 0;
        },
        { concurrency: 2 },
