WP_Query unused code

[mostafaabd]

https://core.trac.wordpress.org/browser/tags/5.3/src/wp-includes/class-wp-query.php#L3411

inside function query on line 3411
$this->query = wp_parse_args( $query );

I think wp_parse_args take 2 arguments to Merge a user defined arguments into defaults array.
but here we only path one parameter
so I think its good to remove this function to be
$this->query = $query;

Thanks for the ticket! For clarity, since the $query parameter can be a string or array here, wp_parse_args() is called to parse a string of query arguments into an array.
