Disassembling and Decompiling Scala Code

Explore the intricacies of Scala compilation and bytecode generation in this 31-minute conference talk from Scala Days Chicago 2017. Delve into the process of disassembling and decompiling Scala code to gain a deeper understanding of how Scala features translate into runnable code. Learn to use tools like javap and decompilers to examine Java bytecode produced by the Scala compiler. Investigate Scala language fundamentals, composition and inheritance, scopes, annotations, and Java interoperability. Discover how to demystify language features and optimize code production through practical examples, including Hello World implementations, case classes, companions, generics, and Future examples. Gain insights into profiler lessons, scalac options, and architecture considerations to enhance your Scala development skills and educate Java developers transitioning to Scala.
