Here are some options with different nuances:
Formal:
* Au revoir: This is the most common and polite way to say goodbye.
* À bientôt: This means "see you soon" and is a more friendly alternative to "au revoir".
* Bonne journée/soirée: This means "have a good day/evening" and is more appropriate for daytime/evening departures.
Informal:
* Ciao: This is a casual way to say goodbye, borrowed from Italian.
* Salut: This is a very casual way to say goodbye, often used between friends.
* À plus tard: This means "see you later" and is a more informal way to say goodbye.
More literal translations:
* Jusqu'à la vue: This is a literal translation of "hasta la vista", but it's not commonly used in French.
* À la prochaine vue: This translates to "until the next view" and is more poetic.
The best way to say "hasta la vista" in French depends on the context and your relationship with the person you're saying goodbye to.
