In the previous class, you learned about the introduction to coding and MakeCode Arcade. In this
                  class, you are going to learn more about MakeCode Arcade.

                  What are Variables?

                  You  have  seen  your  mother  naming  boxes  in  the  kitchen.
                  That box has a little storage capacity and your mother gave
                  it a name such as salt, sugar, tea, etc. Similarly, a variable
                  is a name given to a location in the computer’s memory to
                  store values or data. A variable has a name (for reference),
                  a type (which defines the kind of data it can store and its
                  size), and a value (the actual data).

                  Naming Variables

                  Each variable in a program must have a unique name; you cannot use the same name for more than
                  one variable. The name of a variable serves as an identifier.

                  Rules for Naming a Variable
                  Some rules for naming a variable are as follows:

                      Name your variables in such a way that it describes their purpose.
                      Variable names must begin with a letter or an underscore.

                      No special characters or spaces are allowed in variable names.
                      Uppercase and lowercase characters are distinct.

                      Keywords (reserved words) cannot be used as a variable name. A keyword is a predefined word in
                     any programming language.
                  Creating Variable

                  In MakeCode Arcade, we can create a variable using the Variables block category. Once a variable
                  is created, you need to assign a value to it. This process of assigning a value to a variable is called
                  initialisation. To create and initialise a variable in MakeCode Arcade, follow these steps:
