How Functional Programming Can Help You Write Efficient, Elegant Web Applications

Many things can make software more challenging to understand and, consequently, to maintain. One of the most complex and problematic causes is managing internal mutable states. When the internal state is poorly managed, the software behaves unexpectedly, leading to bugs and fixing, which introduces unnecessary complexity. FP solves this problem by providing immutability mechanisms and more.

Java Champion James Ward on the State of Java and JVM Languages

James Ward is a Java Champion and Google’s Kotlin product manager. In a podcast, Ward agreed that “people are still trapped in the Java world” and called default mutability in Java the “trillion-dollar mistake”. In this interview, he speaks about the state of Java, JVM languages, mutability, and functional programming.

Enhanced Streams Processing with Kotlin’s Sequence Interface

Data structures are an intrinsic part of every programming language, yet Java’s Stream interface lacks vital operations and its complex approach to extensibility gave rise to alternative libraries such as jOOλ and Guava. This article provides an alternative approach that can be easily integrated in any Java project using Kotlin's Sequence interface.

Tutorial: Writing Microservices in Kotlin with Ktor—a Multiplatform Framework for Connected Systems

Ktor (pronounced Kay-tor) is a framework built from the ground up using Kotlin and coroutines. It is a great fit for applications that require HTTP and/or socket connectivity. These can be HTTP backends and RESTful systems, whether or not they’re architectured in a microservice approach.

A Bottom-Up View of Kotlin Coroutines

Recently coroutines have become popular as an alternative to Reactive Programming on the JVM. In many cases the costs of restructuring your code around functional operations for reactive streams outweigh the benefits, so coroutines have emerged, initially for Android, as an alternative solution. This deep dive explores how Kotlin's implementation works under the hood.

An Introduction to Kotlin for Serverside Java Developers

Kotlin is one of the newer languages on the JVM from JetBrains, the makers of IntelliJ. It is a statically typed language which aims to provide a blend of OO and FP programming styles. Kotlin compiler creates bytecode compatible with the JVM, allowing it to run on the JVM and interoperate with existing libraries. We present the main features that might appeal to Java developers.
