Desugaring Kotlin features and their performance impact
Ionut Balosin is a Software Architect and Independent Technical Trainer. He is a regular speaker at software development conferences and meetups around the world, delivering presentations, training courses and workshops. For more details please check his website www.ionutbalosin.com
In this presentation I will try to demystify few Kotlin language features and to present how they are compiled into the bytecode in order to have a better understanding about what happens under the hood.
Also few JMH performance tests are presented between the same functionality written in Java and Kotlin. Few examples:
– extension methods
– optional parameters
– data classes
– when {}
– inlining and its performance costs
– Null Safety and its performance costs
