What does a semicolon do when it’s been added?

#2

Please tell me the details
We cannot help with that much information. What are you adding to?

#3

something like this

local module = {
   number = 10;
}

The first primary use of a semicolon is to have the ability to create multiple statements in one line. Optionally, the semicolon is used in tables and is an alternate separator to ,.

-- multiple statements
local a, b = 1, 2; print(a, b)

-- which is the same as
local a, b = 1, 2
print(a, b)

-- table separator
local t = {
    {"haha", 1}; 2; 3;
}

Additionally, it seems that you can make your code worse by adding the ; in the end of each line. Please don’t hurt me for this.

It’s a requirement in some languages and even some scenarios in Lua, so wouldn’t say it makes your code worse at all. :stuck_out_tongue: Encountered the need for semicolon while debugging a Promise executor the other day.

local foobar = true

Promise.new(function (resolve, reject)
    print("Promise acting")
    ;(foobar and resolve or reject)()
end)
