vJUG24 Session: Functional Data Structures and Java 8 by Oleg Šelajev
Developers love data structures. Applications are often full of maps, trees, heaps, queues, and much more, and we rarely bother to look under the hood to understand the trade-offs between the data structures. This session discusses what makes data structures persistent and why making persistent data structures perform well is hard to do well. It covers what amortized performance is and how lazy evaluation can turn the tables on performance. It also looks at some functional data structures in Java 8 and discusses why are they efficient and when you should use them compared to ones that are built into the JDK. After attending this session, you’ll feel more comfortable with functional data structures and will be a better functional programmer.
