                  Following are the main parts of the Block Editor:

                      Built-in Blocks: It contains all the predefined blocks in the application. They are responsible
                      for handling operations like Math, Text, Logic and Control.

                      Component Blocks: It contains relevant blocks for the components we have added in the
                      Design window.
                      Workspace: It arranges all the blocks for coding in the workspace.

                      Trash: It is used for deleting blocks that are not required.

                      Backpack: It stores the copy of all the blocks even when we exit App Inventor.
