    Type Checking

    Lua supports dynamic typing, which means that variables do not have a fixed data type. The data type of a variable can change during script execution. This flexibility allows you to store different types of values in the same variable.

    Defining a Type

    Use the type function to determine the data type of a variable. The type function returns a string representing the data type of the variable.

    Here's an example of using the type function in Lua:

    local x = 10
    local y = "Hello"
    
    print(type(x)) --> number
    print(type(y)) --> string
    

    In this example, the type function is used to determine the data type of variables x and y. The output shows that x is a number and y is a string.

    Type Coercion

    Lua performs type coercion when necessary to convert values between different data types. For example, Lua automatically converts numbers to strings when concatenating them with strings.

    Here's an example of type coercion in Lua:

    local x = 10
    local y = "Hello"
    
    print(x .. y) --> 10Hello
    

    In this example, the number 10 is automatically converted to a string when concatenated with the string "Hello". The result is the string "10Hello".
