Summary

In this chapter, we learned about the fundamentals of Ruby and its key features. We started with the history of Ruby and the key programming paradigms the language supports that make it unique and powerful at the same time. We then learned about using Ruby code with the IRB and also learned how to write code in Ruby files and execute it. Next, we delved into the standard data types in Ruby, which are number, Boolean, and string. Here, we implemented various operations on variables along with commonly used string operations, such as string concatenation and interpolation.

In the next chapter, we will learn how to work with data structures such as arrays and hashes. We will explore the details of the various powerful methods associated with them, and we will also learn how to create our own Ruby methods and call them, which is the bedrock of day-to-day programming with Ruby.
