What is Ruby?

• A popular language across the world

Ruby Design Principles

• Ruby is a high-level programming language.
• Ruby is an interpreted language. It does not need to be compiled.
• Ruby code is read top-to-bottom, line by line.
• The program that runs the Ruby code is called the interpreter.
• Everything in Ruby is an object.
• Ruby is dynamically typed. Variable types do not have to be declared. The same variable can be reassigned to an object of another data type.
• Strings are mutable objects.

Syntax Best Practices

• Variable names should start with a lowercase letter or underscore
• Use underscores (lower_snake_case)

Resources

• Official Ruby website
• Ruby Help and Documentation
