Are these basically the same?

It's the difference between having an actual computer or having a piece of paper with the word "computer" on it.

in example 1, you are creating an instance of a type. In example 2, you are referencing a type.

Ok, thank you, ^_^.

Just to elaborate on the other answers, both of those lines are in fact legal. The second one is however just a type path. If you set the var to a type path, DM won't complain, but if you go to use any vars belonging to M_S, DS will give you a runtime error because you only set it to a type path instead of a real datum.

The trailing slash in your type paths is unnecessary, but doesn't hurt anything.

Aiight, thank you for explaining why it's like that so I know, I was sort of confused about that. EDIT: What if I go to store the instance of a Datum in a var, how would I do that?

To store an instance of a datum? You'd do this.

var/datum/D = new/datum


You could also do this:

var/D = new/datum
<dm>

But it isn't cast as a datum, meaning if you did this:

<dm>
if(D.type==/datum)


You'd get a compilation error, as DM doesn't interpret D as an instnace of a datum, it's just a normal variable.
