table.concat

Turn table into a string, provided that all of its elements can be coerced into a string. If a separator is specified, then it is inserted between each element. Additionally, concatenation starts at the ith element and ends at the jth.

ExampleConcat an array of numbers
Since numbers are coercible to strings, an array of numbers can be concatenated.
Code 
<nowiki>
print(table.concat({ 1, 2, 3 }, ', '))
    </nowiki>
Output 
1, 2, 3
ExampleConcat a slice of an array
Concatenates an array of both strings and numbers, starting from the 3rd element up to the 5th.
Code 
<nowiki>
print(table.concat({ 1, 2, 3, "a", "b", 4, 5 }, ' ', 3, 5))
    </nowiki>
Output 
3 a b
