The Joy of Kotlin teaches you to write comprehensible, easy-to-maintain, safe programs with Kotlin. In this expert guide, seasoned engineer Pierre-Yves Saumont teaches you to approach common programming challenges with a fresh, FP-inspired perspective. As you work through the many examples, you’ll dive deep into handling errors and data properly, managing state, and taking advantage of laziness. The author’s down-to-earth examples and experience-driven insights will make you a better—and more joyful—developer!
