Example: Boolean
y = false
print(y, type(y))
false boolean
Example: String and number
x = "123"
print(x, type(x))
x = x + 7
print(x, type(x))
123 string
Adding a number to x forces its type to
number.
1.30 number
Example: Function
function add_two(first_value,
second_value)
return first_value + second_value
end
print(add_two(3, 4), type(add_two))
7 function
Example: Table
atable = {1, 2, 3, 4}
print(atable, type(atable))
print(atable[1])
print(atable[4])
