Child psychology. It any pbm to address?

My kid who is 3 yrs old gets anger for silly things and very often,at that moment, she doesn't know what she does.Mostly throws anything that she gets in hand or hits me (happens with parents only).Otherwise she is good at everything. Reached all her milestones on time/early.Understands almost everything and communicates very well.After few minutes, she gets calm and comes to me n clearly says I'm sorry,I won't do this again etc. Still she repeats it next time.Also she doesn't have any children to play with and she behaves better when she gets to play with children n her mood is good for the day. So I was thinking,having no company to play with could be the reason for her such behaviour. It's like she is almost locked at home for the entire week,only during weekends we take her out for playing. After a week,when we take her out, she just wants to run around and doesn't want to hold our hands esp during shopping.For dining,she is good to sit at one place to eat.is it any pbm to address?
