Ruby

"I always thought Smalltalk would beat Java. I just didn’t know it would be called ‘Ruby’ when it did”

Ruby Language:

• Generic, interpreted, reflective, with garbage collection
• Optimized for people rather than computers
• More powerful than Perl, more object oriented than Python
• Everything is an object. There are no primitive types.
• Strong dynamic typing

Everything in Ruby is:

• Assignment – binding names to objects
• Control structures – if/else, while, case
• Sending messages to objects – methods

Ruby is Line Oriented

• Statements are separated by line breaks
• You can put several statements on one line if you separate them by semicolon
• For long statements you can escape the line break with backslash
• After an operator, comma, or the dot in a method invocation you can have a line break and Ruby will know that the statement continues on the next line
• You can have line breaks in strings
