In the Ruby Collections course at Treehouse, you'll level up your Ruby knowledge and start learning about collections. We use two basic data structures to create collections in Ruby: arrays and hashes. These are both examples of "collections" and you’ll work with them a lot in your career as a Ruby programmer. During the course, we'll be writing simple programs that build on what we learned in this course and in previous courses.
In this course we are going to deal with different approaches of storing, accessing, and bending data to your will. By definition, a data structure is a particular way of organizing data so that it can be used efficiently. It's time to get more efficient.
