Creating a menu link programatically in Drupal 8 is easy. You have to provide four values, link title and uri, menu name for which you want to create a menu link, and optionally you can provide a link weight.

Speaking at Drupal Camp Pannonia 2018 was an amazing experience. Sharing knowledge and ideas with the fellow Drupalers is always great, but this Camp that was held in Palić, Serbia was really something special.
