What is Concatenation?
Concatenation is the operation of joining two strings together.
Use Cases

Numbers can be concatenated to strings. In this case they are coerced into strings and then concatenated.
Example
print("Green bottles: "..10)
Output:
Green bottles: 10
print(type("Green bottles: "..10))
Output:
string
Strings concatenated onto numbers must have a space after the number of else they won't be coerced.
Example
print("There are "..10.." green bottles.")
Output:
malformed number near '10..'
print("There are "..10 .." green bottles.")
Output:
There are 10 green bottles.
