You can use a comma to separate things in a list:
Joe, Mary, and me.
You can use one as a thousand separator in numbers:
14,537
with a comma or a semicolon
"comma" is used if we have to use names like more than two then we use there "comma"... two names we use "and" e.g khan and rashid more than two names than we use "comma" e.g khan,rashid,sajid and ahmed
A comma typically goes before "and" when it is connecting two independent clauses. However, a comma is not usually needed before "and" when it is connecting items in a list or when it is connecting two closely related clauses.
When you combine two independent clauses, you need to separate them with a semicolon--not a comma. If you use a comma instead of a semicolon, the result is called a comma splice.
Separate the two independent clauses with a conjunction like "and," "but," or "so." Replace the comma with a semicolon or a colon. Rewrite the sentence by turning one of the clauses into a dependent clause or by breaking it into two separate sentences.
Commas are used to separate items in a list and to separate clauses in a sentence.

No, I do not use commas when I am providing brief answers to questions.
No, don't use a comma after "and" in a series. There are two acceptable comma styles for series. One includes a comma before the final "and" (red, yellow, and blue). The other does not include the final comma (red, yellow and blue).
To separate an introductory phrase from the main clause, as in "After the meeting, we went out for lunch." To set off introductory words or adverbs at the beginning of a sentence, such as "However, I disagree with your assessment." To add clarity by signaling the beginning of the main idea or subject in a sentence, like in "In conclusion, we need to find a solution."
A comma is typically used between a dependent clause and an independent clause in most cases. A semicolon can be used if the two clauses are closely related and the writer wishes to create a stronger connection between them.
It could go either ways?
