Mastering Ruby Closures

The road to Ruby mastery is paved with blocks, procs, and lambdas. To be a truly effective Ruby programmer, it’s not enough just to understand these features—you need to know how to use them in practice. Discover how to write code that is elegant, expressive, and a joy to use, and gain a deep understanding of these concepts so you can work with third-party gems and libraries more easily. Whether you are an intermediate or a seasoned Rubyist, you’ll find good use for these concepts in your code.
