Learn Kotlin in 12 Minutes

Learn the fundamentals of the Kotlin programming language. Kotlin has exploded in popularity over the last few years, commonly used for Android apps, server code, and scripting. We go over variables, operators, strings, if statements, for loops, and functions.

Hi! I’m Rahul, a software engineer with a passion for teaching. I went to Stanford, was a founding engineer at a startup, and have worked at various companies across Silicon Valley. I’m currently an Android Developer and teach an Android class at Stanford. Would love to connect with you! This channel is about tech (especially Silicon Valley), combining tactical how-to guides with interviews.

Other YouTubers would've made a 2hr video out of this but you condensed it down perfectly and explained everything at just the right level. Thank you!

[GeorgAndTheBike]

This is the by far best short introduction to a programming language I have ever encountered. I am super happy that I found your channel!

Damn... I just learnt a lot of Kotlin in 12 minutes. Honestly aside from how refreshing Kotlin is when compared to Java I'm more excited about how similar Kotlin is to Rust and Typescript syntactically. Those are the other languages I'm really excited to learn. This will be a wonderful journey.

Super helpful for someone who already has a good background in another programming language and is able to follow along. I'll definitely be coming back to this as a refresher

[ethiomusic]

This tutorial is what I was searching for several times. Now my confusion is clear a bit. Thank you.

[alejrandom]

Clear, concise, funny, and easy for people who already know, python for example. This man deserves a lot more views.

[wangshiyao]

That's a great syntax review! The single-line null check is so slick!

Getting this much info in 12 minutes without it ever feeling like too much information at once, hats of to you and thanks for sharing!

[brewingentertainment]

This is exactly the crash course you need if you have been trying to migrate from Java to Kotlin for Android. Some of the other concepts are still missing but ofcourse a lot has been covered in this.

[unmeshp]

Thanks for the concise introduction, this is exactly what I was looking for!

[jamesbloxham]

Subscribed (and the first time I've watched one of your videos!). Thanks for putting in the effort to share your knowledge about using Kotlin.

I'm a java backend developer for 12 plus years and I recently started working on my own app and wanted to learn kotlin. I wondered reading the doc may be a bit boring and just wanted a quick tut on Kotlin syntax. So this was a perfect video, only until @3:44. The next thing I know is I'm watching and dancing for songs of late 90s and 2000s, starting from "Call me May be"!

I downloaded Android Studio yesterday and chose Kotlin. I was looking at the screen completely lost. Last time I did any 'code' was HTML web text writing in school like 12 years ago. This helps a lot!

[Kemakemak]

Quick but packed with info. Thanks for this!

[alainrouleau]

Excellent introduction to Kotlin. You covered quite a lot of material in such a short period of time. Thanks!
