The most comprehensive Ruby course with an in-depth overview of coding with Ruby, a popular programming language renowned for its simplicity and elegance.
About This Video
In Detail
Ruby is a language released by Yukihiro Matsumoto in 1995 that bills itself as "a programmer's best friend". Every aspect of Ruby is designed to make programming easier for the developer. There is no better first language if you are interested in learning how to program.
Ruby also serves as the foundation for Ruby on Rails, a popular web framework that powers over 1.2 million websites worldwide. The course offers an extensive introduction to the base language you will need to know if you intend to tackle web development in the future.
The course starts by introducing you to Ruby programming and helps you install Ruby on macOS and Windows OS. You will then look at common programming concepts (variables, arithmetic, output). You will learn objects and methods, strings, numbers, Booleans, methods and conditionals, ranges, arrays, and hashes. After that, you will look at Blocks, Procs, and Lambdas; dates and times; file input and output; and regular expressions. Finally, you will look at classes, modules, and inheritance in detail.
By the end of this course, you will be confident enough to work on the Ruby programming language and bring your programming experience to the next level.
Audience
This course is best suited for the beginning programmers who want to start with an easy, human-friendly language, intermediate coders who are interested in exploring the Ruby language in greater depth, and web development folk curious about the foundation of Ruby on Rails.
Basic text editing skills along with computer skills (web browsing, app installation, file navigation) would be highly recommended to get the most out of this course.
