More often than not, most applications spend a lot of time processing data in order to present it back to the end user. In this course, Working with Data in Ruby 3, you’ll learn to understand the common formats used to represent data in applications (namely CSV and JSON) and how to map the data to the appropriate ruby structures such as arrays and hashes. First, you’ll explore the fundamentals of programmatic structures used to represent data, specifically multi-dimensional arrays, hashes and a mix of both. Next, you’ll discover how to use Ruby’s built in input/output functionality to read files locally and translate them to the structures discussed in the first two sections of the training. Finally, you’ll learn how to consume data from a real world API in your Ruby application. When you’re finished with this course, you’ll have the skills and knowledge to read data and create modern data-driven applications in Ruby 3.
