        }} />

AlertModal and AskModal will return a promise that is fulfilled once confirm is called.

      <button on:click={_modal.open}>Open Modal</button>
    </div>
    <div>
      <button
        on:click={() => {
          _alertmodal.alert(`<h1>Hi! I'm an Alert Modal!</h1>`);
        }}>
        Open Alert Modal
      </button>
    </div>
    <div>
      <button
        on:click={async () => {
          try {
            const data = await _askmodal.ask({ text: 'test' });
            setTimeout(() => {
              alert(`You typed: ${data.text}`);
            }, 500);
          } catch (e) {
            setTimeout(() => {
              alert(`You closed the ask modal without confirmation!`);
            }, 500);
          }
        }}>
        Open Ask Modal
      </button>
    </div>

AskModal datastore

AskModal's ask method expects an object as its first argment. This is the default data that will be stored in the datastore store.

Declaring let:datastore in the AskModal component will provide a way for its inner contents to communiate with the datastore. datastore is a svelte store, so you should use the get function exported from svelte/store in order to access the default values and the set function to edit its values. See example folder for detailed usage.
