I have watched many “tutorials” explaining programming languages. By far, yours is not only an actual tutorial, but a very good one indeed! It has all the core values a good tutorial must have: starts from the basic elements and slowly makes its way up the ladder into more complex functionality, it is slowly and carefully explained with simple examples (I have seen people using frameworks for a graphic user interface just for a hello world in a new language...) and shows the result for both the valid cases and invalid cases as well as ways to tackle common problems that may appear. I had zero knowledge about Kotlin walking into this tutorial and I have quite a good idea of how it works now by only watching the video (when I start actually writing code, this will be consolidated) also thanks for all the Java analogies, they really helped understanding some of the last concepts. 11/10 on this tutorial, 11/10!

This tutorial is great for people who have already worked with Java, but not really for beginners or people who know a language with a very different syntax (like Python). I recommend explaining some things like getters, setters, maps, and when-statements in further detail (or at least put a disclaimer at the beginning of the video that this requires prior knowledge on some of these topics).

@Que_Rico Learning a language on its own likely won't land you a job. I think it's more helpful to think about what you can build with a language. Learning Kotlin can enable you to build a variety of things that likely have different demand in the job market. If you learn to build Android apps with Kotlin there are many jobs out there. Writing backend code with Kotlin could help find a job as well. I'd encourage you to think of what types of projects you want to work on, then determine if Kotlin is a viable tool for that project. If it is, and there's a demand for that work in the job market, then Kotlin would definitely be a positive step towards landing a job.

I would like to get good at Kotlin and maybe eventually learn Swift, because I'd love to get more into Android and Apple app development. With C# I really want to focus on game development via unity, and python can serve as a more general purpose programming language.

UPDATE:WORST TUTORIAL FOR BEGINNERS THE WHOLE VIDEO IS ASSUMING YOU ARE A JAVA EXPERT. I DON'T LIKE JAVA THAT'S WHY I AM LEARNING KOTLIN IN FIRST PLACE......... When I first watched it with no prior programming experience, I didn't understand a thing. Now after having learned OOP, Array, Classes, Main function, fundamentals, etc, from Python, Js, React, I finally understand it. It is a very good tutorial but in my personal opinion it is a too fast paced. But still a great tutorial for Kotlin. To anyone watching this without any programming experience or knowledge please try to learn the fundamentals like "if-else" Before watching this video

I'm really confused, I think some of the things in IntelliJ are different for the newer version, please could you make an updated tutorial.

There is no Kotlin in the IDE, only Kotlin Multiplatform. Fell st the first hurdle.

At first, I thought, "Again, a video for people who don't know how to turn on a computer, " but it quickly got interesting. Everything that you need to know if you already know how to program and you wanna know the syntax of Kotlin.

Well, it is strange. However, the code which you showed at 29:35 doesn't work on my Linux machine. Instead of: "... sayHello(itemToGreet: "Kotlin") sayHello(itemToGreet:"World")..." I had to write "...sayHello(itemToGreet = "Kotlin") sayHello(itemToGreet = "World")..."
@goobar
@goobar 5 лет назад
I can understand the confusion here. I didn't actually type the "itemToGreet" part in that line. After typing the String, the IDE added the label as a visual guide, but it's not actually code. My apologies. I didn't notice that during the recording, and ideally would have explicitly pointed that out

Thank you very much for such a great tutorial! I've learned Java (love it) and to be honest, I'm a bit terrified with that amount of flexibility in Kotlin. All I can think about is "That could be such a mess".
@goobar
@goobar 4 года назад
The flexibility definitely has potential to be abused. I think a good rule of thumb is to take advantage of features to make the code concise, but not so concise that it's no longer easily readable.
