Course description

Ruby expert Jordan Hudgens covers error handling, web frameworks, and algorithms in Ruby in this course. He will begin with a walk through the syntax for basic error handing, emphasizing best practices, followed by a review of the two most popular web frameworks for Ruby: Sinatra and Rails. Hudgens will show how to build two web applications, with the Rails app being a functional blog that includes full CRUD features, and then walk through implementing popular algorithms in Ruby and building the insertion sort and quicksort algorithms. Finally, he will discuss creating a binary search program.

Prerequisites

You should be familiar with basic text editing in a Windows or Linux environment. No prior knowledge of programming is assumed. This course builds on the previous ruby courses: Ruby: Introduction and Classes, Ruby: Variables and Data Structures, Ruby: Input/Output and Gems.
