Explanation:

Series of items: When there are a series of items, the comma can be used to separate them e.g. I went to the market and bought rice, yam, beans and egg.

Introductory word or phrases: The comma can be out after an introductory word or phrase e.g. However, the dog bit the boy.

Interrupting phrases: The comma can be used for an interrupting phrase to give more information.

Compound sentences: Comma can be placed between compound sentences even though each sentence can stand on its own e.g. Tom doesn't like mangoes, so he threw them away.
