                  Imagine you're planning a road trip. To ensure everything goes smoothly, you need to plan
                  each step — from choosing the route and booking accommodation to packing your bags and
                  preparing meals. Each task needs to be done in a specific order to ensure a successful trip, much
                  like how a computer program follows a series of instructions to achieve a goal.
                  A program is a set of instructions written in a particular programming language to complete a
                  task. It is the backbone of software, enabling computers to perform various tasks and allowing
                  users to fully utilise  computing devices. The process of planning the steps and writing  the
                  instructions is known as programming, and the language used to write these instructions is
                  called a programming language.
                  Common programming languages include Python, C++, Java, BASIC, Scratch, and others.

                     INTRODUCING SCRATCH

                  Scratch is an easy-to-learn programming language created by the Lifelong Kindergarten Group
                  at the MIT Media Lab. It has a fun and interactive visual environment that helps beginners learn
                  programming, solve problems, and be creative.
                  Scratch is easier to use than many other programming languages because:

                     It is great for making games, animations, interactive stories, and other fun programs.
                     You can give commands using visual blocks, so there is no need to remember complicated
                     instructions.
                     Scratch uses a block-based visual programming interface where users drag and drop command
                     blocks to create scripts.
                     The blocks are colour-coded and designed like puzzle pieces, making it easy to arrange them
                     logically.
