Commas

A comma (,) is a punctuation mark used to mark the divisions in text (as may be caused by phrases, clauses or conjunctions). Commas are used in lists to separate list items and in numbers to aid reading.

You can only connect two complete sentences with a comma if there’s a coordinating conjunction (For, And, Nor, But, Or, Yet, So or FANBOYS), between them.

Use a comma between two coordinate adjectives that describe the same noun.

Use a comma to highlight additional, non-essential information about a noun.

Make sure you place commas correctly in quotes.

Put a comma before “while” to contrast two things.
