remove google map link

Hi. I found a post related to this question but it’s 2 years old. It contained the following:
add_filter( ‘the_job_location_map_link’, ‘remove_the_job_location_map_link’ );

function remove_the_job_location_map_link( $link ) {
return strip_tags( $link );
}

My question is:
1) does this still work
2) where does this code get placed?

Thanks.
