Since WordPress 5.5.0 it has been possible to pass arguments/data to the Get template part function. This was a much requested feature, and is great for reusing components throughout a site.
To reuse a component, call it in your template file. This example assumes a component named 'reusable-component.php' is in a 'template-parts' folder in your theme. The third argument is where we pass data to the component as an array:
<?php get_template_part('template-parts', 'reusable-component', ['foo' => 'bar']); ?>
In the component, the 'foo' variable can then be accessed inside the $args array:
<?php // Prints 'bar' to the page` echo $args['foo']; ?>
