Why 2 different entries belongsToMany(Tag::class) and belongsToMany('App\Tag') if the result is identical?

Question

Laravel

It seems to work fine with both entries, in one option we specify the class, and in the other through the class path. I do not see the difference, how best to record?

Answer 1

I propose to get acquainted with the language, more specifically with php version 5.5: php.net/manual/en/language.oop5.basic.php

Answer 2

Everything is obvious. If you use namespaces (and you do), it's more convenient to specify the class name without a namespace.
If you have a model in the namespace `Very\Super\Long\Name\Spa\ce\` then which entry will be shorter (do not forget to add a class to the "use" section if required):

belongsToMany( Tag::class )

or

belongsToMany( 'Very\Super\Long\Name\Spa\ce\Tag' )

?
This is the first benefit.
The second benefit - if you suddenly decide to rename the `Tag` class to `Metka` - you can easily do this by refactoring, and if you have a class specified by a string, then you will look for a mention of a string with the class name in the files. The same thing - if suddenly you need to move the Tag class from one namespace to another.
Well, definitely read the mana.
