Writer’s Note: For all the aspiring developers reading this blog you are in for a treat. For the non-nerd entrepreneurs, I won’t bore you with technical jargons; instead I’ll introduce you to Kotlin in the simplest way possible

A Brief History of Kotlin: (How did this beast come to exist?)

In July of 2011, a very smart group of individuals (collectively known as JetBrains) unveiled to the world their prized invention, Kotlin.

Kotlin for Android developers has become a token of excellence ever since. It was only 5 years later that the first official version 1.0 released in 2016. The most recent Kotlin version is 1.3.10 released in November of 2018.

(A Tip For Entrepreneurs: If any company tries to pull a fast one on you just ask them which version they are using currently. Ask a bit technical questions to show them who’s the boss, but do slight research beforehand.)

Kotlin becomes the Primary Choice: (Why Google made Kotlin their Number 1?)

Andrey Breslav (father of Kotlin) said that Kotlin for Android developers is designed to be an industrial-strength object-oriented language, and a “better language” than Java, and they proved it all the way through. Features like Interoperability with Java, Conciseness, and Android Studio support were reasons enough for Google to make the official switch from Java to Kotlin. But they hit jackpot with this new language (also considered as the Swift of Android).

(A Tip For Developers: Great companies and startups like Google, Netflix, Uber, and many others are already using code base of Kotlin. It’s a great time to make the jump and migrate from Java to Kotlin.)
