Ruby is a type of computer language that people can use to make electronic machines do different things. It is kind of like being able to talk to a robot in a way that it understands.
The words in Ruby have different meanings and can be put together in different ways to make the computer do different things.
Like you have rules to follow at home or in school, Ruby also has rules to follow. These rules are called syntax, and they tell people how they can use the different words in this language.
When someone is using Ruby, they need to make sure they follow the syntax rules. Otherwise, the computer might not understand what they are trying to say.
Ruby can be used to build many different types of things, from websites to cool video games, and much more!
