Scratch is a block-based programming language designed for children. It offers a
free toolkit that lets them create their own games, animated stories, and interactive
art, and share their work online. Children can drag and combine code blocks to
make various programs, such as animations, stories, musical instruments, and
games.
PROGRAM AND PROGRAMMING LANGUAGES

task. These instructions are written in a computer language, which has a specific
set of rules known as Syntax. Syntax acts like grammar for the computer language.
Computer languages are the means by which humans communicate with
computers. These languages use a combination of keywords, symbols, and syntax
that the computer can understand and execute to create programs.
The process of writing a program is called programming, and the individuals
who do this are known as programmers. Computer languages are typically
categorized into two main types:
