Difference between "" and ''

When getting a specific string, what’s the difference between " " and ’ '?

There is no difference, just use whichever you prefer.

There’s a difference, there are some typos you can get while using ‘’ and “”
Example:

Though, I would not be the person to tell what is precisely the difference between both

local a,b = "''", '""'
They’re less different and more reciprocal of each other.

Difference is double quotes can’t contain double quotes without escaping, single quotes can’t use single quotes without escaping

print("What's up? \"The sky!\"")
print('What\'s up? "The sky!"')

I think this shows it quite well. I personally don’t use single quotes because I’ll have to escape apostrophes for contractions, which are extremely common (like this post uses 4 contractions already!). And in other statically typed language there is a distinction made between strings and single chars, the former using double quotes and the latter using single quotes.

I assumed you meant

print("Hello world!")

vs

print('Hello world!')

In this case it wouldn’t make a difference unless you have another " or ’ in the string like @sjr04 stated

In lua both represent strings.

In other languages '' typically represents a single character whereas "" typically represents an array of characters (a string). This changes depending on the language, however both are literals.
