Get commerce product field value drupal 8

Get commerce product field value drupal 8:

In preprocess function:

function HOOK_preprocess_commerce_product(&$variables) { 

  $product = $variables['elements']['#commerce_product'];

$fieldValue = $product->get('field_name')->getValue()[0]['value'];

}

This would also work I think
$product->field_mchine_name->value
