wordpress get the_excerpt by post id

In Current 4.9 or preview versions we cannot get the_excerpt or get_the_excerpt by post ID so here is a little bit hack code to get excerpt paragraph of post by postID with alternate code

$postID=1;
$postDATA = get_post($postID);
$wordLength = 15;
echo wp_trim_words( strip_shortcodes($postDATA->post_content) ,$wordLength);
