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)
