Suppose, you are organising a birthday party. You need to make sure everything happens
smoothly, from sending invitations to arranging the cake, games, and music. Each step must
be followed to make the party a success, just like how a computer program follows a set of
instructions to achieve a result.
A program is a set of instructions written in a specific programming language to do a specific
task. It is the fundamental building block of software, enabling computers to perform a wide
range of tasks and enabling the users to utilise the capabilities of computing devices for various
purposes. The process of deciding the steps and writing instructions is called programming and
the language in which the instructions written is called programming language.
The programming languages that we can use to do our work can be Python, C++, Java, BASIC,
Scratch, and many others.
INTRODUCING SCRATCH
Scratch is an easy-to-learn visual programming language developed by the Lifelong Kindergarten
Group at the MIT Media Lab. It has a playful and powerful interactive visual environment that
serves as a stepping stone into the world of programming for beginners to explore computational
thinking, problem-solving, and creativity.
Scratch is easier to use than most other programming languages because:
It is one of the best programming languages for making games, animations, interactive stories,
and other visually rich programs.
The commands are given using visual interactive tools, so there is no need to remember the
commands to do a task.
