Covers the essential features of programming in Kotlin and its core libraries, including the latest features and its interface to JavaScript for both DOM and Node.js programming.


Differences to JavaScript

  • Syntax differences
  • Type differences
  • Read-only and read-write variables
  • External functions and data
  • Type inference
  • Operator differences
  • Coding conventions
  • File and package conventions
  • Interacting with the DOM
  • Interacting with the Node.js

  • Function arguments
  • Anonymous functions
  • Lambda functions
  • Function references
  • Inlining
  • Scope functions


  • Lists
  • Sets

Object-Oriented Programming

  • Inheritance

  • Interfaces
  • Nested and inner classes
  • Operator overloading
  • Objects and companion objects
  • Extension functions and properties


  • Generic types
  • Generic functions

Kotlin is a modern language that known mainly for its ability to write code for the JVM and Android. Kotlin can also target JavaScript applications for both client-side programming via the DOM and server-side programming via Node.js.

This course covers all the major features of the latest release of Kotlin and its interoperability with JavaScript.


On successful completion of this course, participants will be able to:

  • Write and compile Kotlin programs
  • Run and debug Kotlin programs in a browser
  • Run and debug Kotlin programs in Node.js
  • Understand the differences between JavaScript and Kotlin
  • Utilise the artifacts in the Kotlin library
  • Use the object-oriented features of Kotlin
  • Use the functional features of Kotlin


This course is aimed primarily at programmers who are interested in developing web applications in Kotlin or using Kotlin with JavaScript code. Engineers, analysts and managers will also find it useful.


Participants are expected to be familiar with JavaScript for DOM and/or Node.js programming. Those who wish to learn Kotlin as a generic language would be better served by our Kotlin Programming course.
