Kotlin is quickly joining the ranks of the most popular programming languages. Now that Google supports Kotlin for Android app development as the primary choice over Java, we’ll only see more developers making the switch. So if you’re looking to get started with Android app development, then you’ve come to the right place.

This course will be your guide on getting started with Kotlin. We’ll go over all the language basics including variable declarations, data types and the type system to conditions, loops, and functions.

After this course, you’ll be able to write simple Kotlin scripts and applications. With this solid understanding of the language basics, you’ll be able to more easily follow more advanced material covering functional and object-oriented programming.

What a brilliant course, its not too long so its fairly easy to get through in a weekend. Goes through the fundimentals of Kotlin in just the right amount of detail. I would recommend this as a first step into Kotlin language

"Brilliant course"

I have completed the course and I have to say that it's extremely well done

The examples used are clear and easy to follow

The code is very clean and the instructor strives to write clear and concise code and he explains concepts very clearly

Kudos for a job well done!

"Extremely well done"

Alan J.

Clear explanations, and well organized. Highly recommended.

Excellent course. It's a beginner course in programming, but even as a Java programmer I've been able to remember a lot of things and get productive quickly in Kotlin. The course is well structured and the teacher knows the subject (I bought another course from the teacher).

"Excellent course"

Kotlin Crash Course for Programmers

In contrast to `while` loops, Kotlin's `for` loops work a bit differently than you may be used to from other languages.

## `for` Loops

Kotlin's `for` loops are different from many other languages because they're used in the same manner as *for-each loops* (or *for-in loops*). Thus, you always give an *iterable* to the `for` loop over which it iterates:
