Suggestion for blog.php

I added a Recent News section to my Home page (a list of blogs), but it showed the oldest blog posts, not the newest ones.

I managed to solve this by adding an orderby argument. Here are the first 40 lines of the modified blog.php file, with added content in bold:

<?php
if ( ! get_theme_mod( 'pure_portfolio_enable_blog_section', false ) ) {
	return;
}
$content_ids  = array();
$content_type = get_theme_mod( 'pure_portfolio_blog_content_type', 'post' );
if ( $content_type === 'post' ) {
	for ( $i = 1; $i <= 10; $i++ ) {
		$content_ids[] = get_theme_mod( 'pure_portfolio_blog_content_post_' . $i );
	}
	$args = array(
		'post_type'           => $content_type,
		'post__in'            => array_filter( $content_ids ),
		'orderby'             => 'post__in',
		'posts_per_page'      => absint( 10 ),
		'ignore_sticky_posts' => true,
		'orderby'   => array(
			'date' =>'DESC',
			'menu_order'=>'ASC',
			/*Other params*/
		),
	);
} else {
	$cat_content_id = get_theme_mod( 'pure_portfolio_blog_content_category' );
	$args           = array(
		'cat'            => $cat_content_id,
		'posts_per_page' => absint( 10 ),
		'orderby'   => array(
			'date' =>'DESC',
			'menu_order'=>'ASC',
			/*Other params*/
		),
	);
}
