"literal strings" between double quotes
and single characters, like `

-->shows the output of a statement or, occasionally, the result of an expression:
print(10) --> 10 13 + 3 --> 16Because a double hyphen (

<-->to indicate that something is equivalent to something else:
this <--> thatThat is, there is no difference to Lua whether you write
