Ruby Langauge Fundamentals
Ruby is an interpreted, high-level, general-purpose programming language that is dynamically typed and uses garbage collection. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. In this path you will learn the basics of Ruby and more advanced topics such as object-oriented design, code organization and testing.
Ruby: The Big Picture
1h 12m
Description
There are plenty of programming languages around–but for many programmers, Ruby is special. At first, it seemed to come out of nowhere, taking over the world of web applications with frameworks such as Ruby on Rails. But Ruby isn’t just for the web: it’s a great all-purpose language, perfect to write scripts or process data.
In this course, Ruby: The Big Picture, shows you what Ruby looks like–and what makes it unique. First, you'll look at Ruby from 10 miles high, examining its strong and weak points. Next, you'll view snippets of Ruby code. Then, you’ll see why so many developers are in love with this weird language from Japan.
After watching this course, you’ll know enough Ruby to answer one all-important question: is this language for me, and why should I learn it?

Reading and Writing Data with Ruby
1h 37m
Description
Processing data from a third party provider in JSON or CSV format is essential for communicating with other systems and representing complex information. In this course, Reading and Writing Data with Ruby, you’ll learn to read and parse data in JSON and CSV format using Ruby’s standard library and interact with various sources that make use of these formats including local files and information returned by web services. First, you’ll explore how data is structured using either JSON or CSV including where one format is used over the other. Next, you’ll discover how to read and write JSON and CSV data to and from a local file and how it is represented natively using Ruby’s data types. Finally you’ll learn how to apply processing of JSON data using Ruby by interacting with an actual web service. When you’re finished with this course, you’ll have the skills and knowledge of reading and writing data with Ruby needed to create applications that process data from a file and interact with third party services that use JSON to represent data.
