Ruby's Basic Features: Blocks, Loops, Arrays & more
Like any other programming language, Ruby has a number of basic features that make up the code. Learn what these features are and how to use them in your code.
Modules
In any programming language, you need some way to prevent naming clashes. This is especially true when you're using at least one third party library, where you have no control over the naming scheme. In the past, naming conventions would be used. It's not uncommon to see C programs with names like [i]mylibrary_some_function[/i]. However, Ruby has a more powerful solution: modules.

How Can I Store Key/Value Pairs in Ruby?
Storing key/value pairs in Ruby doesn't always need to be accomplished by using a hash. You can also use the Struct and OpenStruct classes.

Input and Output
The basic IO methods are often overlooked by many Ruby programmers. How often have you used the gets and puts methods without giving them a second glance? Learn all the features of these methods to better put them to use in your code.
