What is the Difference Between Comma and Semicolon?

The main difference between commas and semicolons lies in their use and the degree of separation they provide between phrases, clauses, or sentences. Here are the key differences:

Commas:

• Separate two complete sentences joined by a coordinating conjunction (and, but, or, nor, for, so, or yet).
• Separate items in a series, including coordinate adjectives.
• Set off parenthetical elements, such as an appositive or nonrestrictive relative clauses.
• Set off transitional phrases.
• Follow introductory clauses and phrases.

Semicolons:

• Connect two independent clauses without using a coordinating conjunction.
• Separate three or more items in a series that already have commas in them.
• Connect independent clauses with connecting words like "however," "moreover," and "thus".

In summary, commas are used to separate complete sentences joined by coordinating conjunctions, items in a series, and to set off parenthetical elements and transitional phrases. Semicolons, on the other hand, are used to connect independent clauses without coordinating conjunctions and to separate items in a series that contain commas.

Comparative Table: Comma vs Semicolon

The main difference between a comma and a semicolon is their use in punctuation and the hold they place on the flow of a sentence. Here is a table summarizing their differences:

In the context of programming, specifically in Lua, both commas and semicolons can be used interchangeably to separate elements in a table. However, semicolons are also used to 'end' a line of code. In general, the choice between using commas or semicolons is based on personal preference and the desired appearance of the script.
