I have seen the post on how to create menu items programmatically in Drupal 8, but how do I update or delete menu items in D8?
Clarification: by programmatically I mean dynamically so yaml config files are not going to help.

@4k4 "Remember that menu items are entities in D8" is perhaps what you are saying? It is helpful that you are pointing that out, if that is what you are saying. – Duncanmoo May 4 '17 at 12:16

I think the documentation is very helpful. – 4k4 May 4 '17 at 12:33

First you will have to load the entity. Either way works:
$menu_link = MenuLinkContent::load($menu_link_id);
or ...
$menu_link = \Drupal::entityTypeManager()->getStorage('menu_link_content')->load($menu_link_id);
Next you can update value using set() method or through the magic method __set...
$menu_link->expanded = TRUE;
To save, simply call the save() method.
To delete, simply call the delete() method.

1You are using a mlid there, might seem like I am appending an additional question but where would you get that from, ie. how do you traverse a menu's tree? – Duncanmoo May 4 '17 at 12:20

In which hook we need to do all these? I am creating a theme and I override menu--main.html.twig file to style the menu. This code has to go in .theme file? in which hook? – siddiq Dec 11 '17 at 1:37

I had to do some thing like ....
//menuLinkManager = 'plugin.manager.menu.link'
$result = $this->menuLinkManager->loadLinksByRoute('entity.node.canonical', ['node' => $node->id()]);
foreach ($result as $menu_item) {
if (is_object($menu_item)) {
$id = $menu_item->getPluginDefinition()['metadata']['entity_id'];
$menu_link = $this->entityTypeManager->getStorage('menu_link_content')->load($id);
$menu_link->enabled = 0;
$menu_link->save()

Probably too late I did like:
$menu_handler = \Drupal::service('menu.link_tree')
->load("menu-name", new \Drupal\Core\Menu\MenuTreeParameters());
foreach($menu_handler as $key=>$value) {
if('Name' == $value->link->getTitle()) {
$link = $value->link;
$link->updateLink(
[
'enabled'=>'1',
'title'=>'New Name'
],
true
);
}
}
