Welcome to the forum.
We have multiple threads on the use of commas (see Similar Threads below) and there are plenty of online sites where you will find the information. We are not here to replace your own research and your grammar/punctuation books.
If you come across a sentence where you don't understand why it has been punctuated in a certain way, feel free to ask us to explain.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
