Philosophy
- Focus is on the programmer rather than the machine. i.e. maximize programmer efficiency.
- Principle of least astonishment - behave in such a way that minimized the confusion of experienced Ruby programmers.
- Ruby is an object-oriented scripting language.
- Multi paradigm :
- Scripting : automate tasks within some environment
- Imperative : traditional control structures
- Object oriented : everything is an object
- Functional : Also exists. Computation proceeds via the evaluation of functions that depend only on their input, not program state.
Classes and Inheritance
class MyClass
@boo #instance variable
def my_method
@foo = 2
end
end
