Answer:
a comma is important for a couple reasons.
Explanation:
A comma can avoid a run on sentence, and completely change the type of sentence (eg. compound, complex, run on, etc.). It can also change the whole meaning of what's being said in the sentence. For example: "Let's eat, Jayden!" compared to, "Let's eat Jayden!" have completely different meanings because of the comma.
