callApi().then(function (result) {
  try {
    if (result.status === 0) {
      model.apiCall.success = true;
      if (result.data.items.length > 0) {
        model.apiCall.numOfItems = result.data.items.length;
        if (isValid(result.data) {
          model.apiCall.result = result.data;
        }
      }
    }
  } catch (e) {
    // suppress errors
  }
});


//instead we can do this 
callApi().then(function (result) {
  if (result.status !== 0) {
    return;
  }
  model.apiCall.success = true;
  if (result.data.items.length <= 0) {
    return;
  }
  model.apiCall.numOfItems = result.data.items.length;
  if (!isValid(result.data)) {
    return;
  }
  model.apiCall.result = result.data;
});
