Naive JSON.stringify() in Sass (handles strings only)

json-stringify.scss

@function json-stringify ($map) {
  $result: '{';

  @each $key, $value in $map {
    $result: $result + '"#{$key}":';

    @if type-of($value) == 'map' {
      $result: $result + json-stringify($value);
    } @else {
      $result: $result + '"#{$value}"';
    }


    @if index($map, ($key $value)) != length($map) {
      $result: $result + ',';
    }
  }

  $result: $result + '}';

  @return $result;
}
