Apple builders could have been glad to see Swift rapidly rise within the wake of Objective-C (although some nonetheless suppose it is “crap”), however Kotlin, an open supply, statically-typed various to Java for Android builders, has some dancing—Sound of Music model. “Since the beginning of Android, we developers have been stuck with a dated version of a dated language,” bemoaned Viacom developer Danny Preussler, however Kotlin, in response to Basecamp developer Dan Kim, “makes me happy.”
Odds are it could do the identical for you. Here’s why.
The Dark Ages of Java
Though Kotlin continues to be comparatively puny when it comes to recognition, it has blazed into the top-50 languages on the Tiobe Index, and in addition leaped to #46 on the Redmonk rating, prompting Redmonk’s Stephen O’Grady to put in writing: “The big question facing Kotlin then isn’t whether it will experience gains based on interest – the language already has jumped nearly twenty spots in a year’s time which is very unusual – but how quickly, and to what degree.”
Why? After all, Kotlin has been round since 2010, producing solely “low-key buzz,” as developer Steve Yegge termed it. That buzz, nevertheless, has steadily grown, and when Google threw its weight behind Kotlin, the thrill turned a deafening roar.

Suddenly, the Android neighborhood had a programming language that felt like Swift. (Though, once more, not everybody thinks this can be a good factor.) More importantly, it felt like one thing written for contemporary improvement. As Jessica Thornsby has identified, Java is hardly a contemporary language and, even because it slowly evolves, Android solely helps a subset of these evolving options. Yegge was much less diplomatic:
If the language you are utilizing occurs to be Java, then you definately’ve little question realized that by the point Java turns into a very good language, you may be lifeless. Loooong lifeless. I do know we do not wish to ponder our personal mortality, however if you plot the trajectory of Java from its delivery 20+ years in the past to its full knee and hip substitute with Java eight, you may’t assist however marvel, “Am I going to be stuck with this for literally the rest of my life? What if this is as good as it gets?”
It’s an odd juxtaposition: Fast-moving cell improvement with a glacially slow-moving programming language. The two do not appear to combine, venerable as Java could also be.
But there’s extra to Kotlin’s recognition than a robust need to desert Java by the wayside.
Getting that spring again in your step
For Kim, “Kotlin makes me a happier (better) programmer.” The causes, he wrote, are a number of:
Writing code that is concise, clear, and expressive makes me pleased. Focusing on artistic options to enterprise issues, not boilerplate and ceremony, makes me pleased. Feeling an intense motivation to be taught, which was lacking within the Java days, makes me pleased.

Getting to that dopamine rush of happiness, in flip, comes tremendous rapidly. Preussler calls this out, declaring: “The studying curve of Kotlin is de facto low.”
Yegge, impressed by how “gorgeous” Kotlin code is, took this theme and ran with it:
I took [Kotlin] for a take a look at drive. And inside possibly 4 or 5 weeks, identical to that, I used to be rewriting my 20-year-old recreation server platform in Kotlin. One month of utilizing Kotlin and I used to be offered….It solely took possibly three days to be taught Kotlin nicely sufficient to begin busting out code, totally conscious that I did not know what the hell I used to be doing, however realizing the language and IDE have been doing an amazing job of retaining me out of hassle anyway.
Not solely is Kotlin straightforward to be taught, however, he wrote, “Everything you write in it feels like you made something cool.” Can a developer write cool code with Java? Sure. But it comes at a value Yegge wrote:
Kotlin is simply butter: Tailor-made for us Java programmers who’re nonetheless type of scratching our heads over Java eight’s parallel streaming filterable accumulating scheduled completable callbacking futuring listening forking executor noun kingdom. Kotlin offers you all the identical energy — considerably extra, really, with its coroutines assist — however makes it method simpler to say stuff. Java eight helps you to say fascinating issues, however you must do it with a mouthful of sand.
In quick, life simply obtained sunny for Android builders. As developer James McShane informed me, Kotlin “makes me enjoy my daily work more.”
All of which is nice information for Android. Already the market share chief, Android improvement could rapidly emerge as a labor of affection, not of responsibility. At Google’s announcement of Kotlin assist, one developer gushed, “I’m almost crying right now.” Fortunately for Android, these are lastly tears of happiness, not Java-laced despair.
