WP_Theme_JSON_Resolver::theme_has_support() WordPress Method

The WP_Theme_JSON_Resolver::theme_has_support() function checks whether a theme has support for a given feature. This function is useful for checking whether a theme supports a particular feature before using it. For example, if you want to use the post-thumbnails feature in your theme, you would first check if the theme supports it before adding the code to your theme. This function returns true if the theme has support for the given feature, false otherwise.
