Interjections are words that express strong emotions. They are not grammatically connected to the rest of the sentence. Interjections that express anger, excitement, surprised or urgency is followed by an exclamation mark. Other kinds of emotions and expressions are followed by a comma.
Examples (using the exclamation mark):
