Get type of object in Lua

In Lua, the type of an object can be determined using the type() function. This function takes an argument and returns a string representation of the data type of the argument. Below are some examples:

-- Example 1: Type of a string
str = "Hello World"
print(type(str))  -- Output: string
 
-- Example 2: Type of a number
num = 42
print(type(num))  -- Output: number
 
-- Example 3: Type of a table
tbl = {1, 2, 3}
print(type(tbl))  -- Output: table
 
-- Example 4: Type of a function
function foo()
  return 1
end
print(type(foo))  -- Output: function
 
-- Example 5: Type of a nil value
nilval = nil
print(type(nilval))  -- Output: nil

In the above examples, we have initialized variables with different data types and used the type() function to get their respective data types. The output of each example shows the string representation of the data type of the argument passed to the type() function.
