In this article, Toptal Software Engineer Nikita Tuk outlines the 10 most common mistakes that developers make—and how to avoid them.

Implementing applications that deal with complex concurrent behavior has always been a challenging aspect of programming. Various paradigms exist that promise a solution to this problem in different ways. RxJava is a Java library that enables Functional Reactive Programming in Android development. It raises the level of abstraction around threading in order to simplify the implementation of complex concurrent behavior.

In this article, Toptal Freelance Software Engineer Christopher Arriola gives us a detailed walkthrough of RxJava and how it fits into the realm of Android development.

Kotlin is a new, expressive, general-purpose programming language powered by the same virtual machine technology that powers Java. Since Kotlin compiles to the JVM bytecode, it can be used side by side with Java, and it does not come with a performance overhead.

In this article, Toptal Freelance Software Engineer Ivan Kušt gives us a walkthrough of 10 major features of Kotlin that help avoid boilerplate code and, more importantly, save time.

As a result of smartphones and mobile applications becoming so popular, web developers have been looking for ways to create mobile applications using JavaScript.
