These are notes I’m taking while reading the Programming Ruby book. It’s excellent.

General Ruby

• use parens in all but the simplest cases
• single quotes for non-escaped strings, double quotes induce more work
• escaped strings replace with binary val
• double quotes also used with expression interpolation #{name}
• the last expression evaluated by a method is the return value; no need for return unless being of utmost verbose

Classes

• classes are never closed. you can always add methods to an existing class by opening the class like you would a folder or file

Cool and unforgettable features

• statement modifiers: ** expression followed by if or while and the condition ** (ex. puts “danger!” if radiation > 3000)
