We should keep in mind when two independent clauses are joined by a coordinating conjunction, a comma is also used with the coordinating conjunction, but if the two independent clauses are nicely balanced then we can remove the comma.
Example: It was raining very hard, but he managed to go to school.

Example: Joshua drinks beer, scotch, rum and wine.
As we know and, but are two important coordinating conjunction, but it is often questioned whether we can begin a sentence with and or but.
