I just started learning Japanese and I came across the particle "の", I understand that it is used between two nouns but I didn't really understand if you can use it only once in a phrase or if you use it between every two nouns.
@Ragaroni's answer is very correct. In general のconnects, two words and show what/who possesses what. However, when you write Japanese (in the future), do not use it too much because it doesn't look nice, the same reason we should not abuse "and" in English.
This is not a grammar suggestion but literature advice, rather.
Hope it helps too! =)
