A computer also follows stepwise instructions to complete any task known as a
program. We can define a program as a set of systematic instructions that direct
the computer to do specific tasks and get the desired results. Programs are written
in a special language known as a programming language. The person who writes
these programs is known as a programmer.
In this chapter we will learn about Scratch. It is a block-based programming
language.
WHAT IS SCRATCH?
Scratch is a visual programming language used to create computer
animation, games and stories. Visual programming means that
rather than having to type the code (instructions), we use blocks of
code that we put together to create our projects. This makes it easier
to get started. It enables us to see the results of our work quickly and
even includes graphics and sound to it.

Scratch was created by Mitchel Resnick at the MIT Media Lab in 2007. FACT
ADVANTAGES OF SCRATCH
Scratch is simple, easy to understand and learn. It is used more than many other
programming languages for the following reasons:
We don’t have to remember or type commands, we can just drag and drop them
as we desire.
Commands fit together like puzzle pieces, so we get clear visual hints about how
to combine them.
We can create animations, quizzes and stories.
We can create and share our Scratch project online on the Scratch website.
In how many languages is Scratch available?
