    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:

                                                     1  Visit https://arcade.makecode.com/.

                                2  Click on the New Project
                                button. The Create a Project
                                dialog box appears.
