GRAMMAR:
だよね breaks down as だ (copula) + よ (assertion) + ね (seeking agreement). After verbs and い-adjectives, the だ is dropped: (たか)いよね, ()くよね.

Used predominantly by both male and female speakers. The variant だよな is more masculine.

As a standalone response, だよね functions like "I know, right" or "exactly" in English.
