In this course, Ruby expert Jordan Hudgens examines the basic building blocks of the program and dives deep on its various data structures such as arrays. He will also discuss how Ruby uses dynamic typecasting and teach you how to use the struct class to encapsulate data with methods and behaviors. With a better understanding of data structures in place, Hudgens will then walk you through how to automate tasks in Ruby such as calculating sums.
Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.
