How to increase the number of 'News' columns from homepage?

The number of ‘News’ columns can be increased by adding the below-wrote code on cPanel > File Manager > public_html > wp-content/themes/wpjobster-child > script.js file.

Hooks.add_filter( 'wpj_news_items_filter', wpj_change_news_items_number, 1 );
function wpj_change_news_items_number( items_no ) {
return 4; // replace '4' with any number (4 is the number of columns)
}

This is how News will be displayed depending on how many columns you set on the code.
