Here's how it's used:
* "Has just" - This is the most common use. It describes an action that has just happened.
* Example: _Il vient de partir. _ (He has just left.)
* "Just came from" - This is used to describe where someone or something recently came from.
* Example: _Elle vient de la librairie. _ (She just came from the bookstore.)
It's important to note that "vient de" is a present tense conjugation of the verb "venir" (to come) followed by the preposition "de".
