A comment is text within a program that is not being executed. It can provide additional information to support understanding the code.
In Lua, two consecutive dashes are used to create single line comments. The compiler does not read any text after
-- on the same line.
function sum(number1, number2)-- this is a commentsum = number1 + number2return sumend
The comment does not affect the function.
In Lua, multi-line comments are created using the
--[[ syntax to start the comment, and
]]-- to end the comment. The compiler does not read any text in between.
--[[ this is a multi-line comment.The compilerwill not run codewritten in between. ]]--
