Remove comma from while statement

Im looking for a way to output my wordpress custom fields in this format:

  "genre": [
        "genre 1",
         "genre 2",
         "genre 3"
  ]

using this code:

"genre": [
  <?php if( have_rows('genres') ):
      while ( have_rows('genres') ) : the_row();
          $genre = get_sub_field('genre');
          ?>
          "<?= $genre; ?>",
    <?php
      endwhile;

  endif; ?>
  ]

But the result (logically) has a comma at the last genre, which creates errors.

"genre": [
        "genre 1",
         "genre 2",
         "genre 3",
  ]

How can i fix this?:

I don't know Wordpress (and never will) but that's JSON, why not:

while ( have_rows('genres') ) : the_row();
    $genres[] = get_sub_field('genre');
endwhile;

echo json_encode(['genre' => $genres]);
