Introduction to Kotlin

Nivå: Foundation

Learn Kotlin to increase developer efficiency and the creation of powerful full-stack applications on a wide range of platforms. Kotlin is one of the fastest growing programming languages due to its streamlined syntax, powerful type safe constructs and being able to target multiple runtime platforms. Kotlin allows developers to mix object and function oriented programming styles to deliver efficient, clear, readable code. Gain experience building Kotlin functions and classes and efficient, safe asynchronous code using coroutines.

Nyckelfunktioner:

  • After-course instructor coaching benefit

Introduction to Kotlin FAQs

  • What’s so good about Kotlin?

    Kotlin is a professional programming language which has been designed to improve code quality and developer efficiency. Through coroutines, it provides an innovative and reliable solution to the challenges of asynchronous execution.

  • What is a coroutine?

    Modern code makes extensive use of asynchronous event driven code. There have been may attempts through constructs such as threads, Promises and Observables to improve the handling of these events. Coroutines provide a simple and elegant solution to the challenges of asynchronous code that work on any platform without the risks associated with techniques such as threading.

  • Can I take this Kotlin training online?

    Yes! We know your busy work schedule may prevent you from getting to one of our classrooms which is why we offer convenient online training to meet your needs wherever you want, including online training.
