What is Kotlin ?
Kotlin is a modern programming language that compiles to Java bytecode. It is free and open source, and promises to make coding for Android even more fun.
Kotlin was created by JetBrains, the company behind IntelliJ IDEA (Android Studio is based on IntelliJ IDEA). Since Google announced official support for Kotlin development on Android at Google I/O 2017, it has rapidly become the third-most loved language in the world, according to Stack Overflow’s annual developer survey.
It rose to popularity in 2016 when Google announced Kotlin as an officially supported language for Android development.
What is Kotlin used for?
1) Compatibility with Java - As Kotlin compiles down to Java bytecode, it can be used anywhere that Java is used. This means you can use Kotlin in both your frontend and backend codebases without any performance hits or compatibility issues.
2) Powerful Type System - Kotlin's type system is very powerful, which allows programmers to define types that are more specific than those provided by the JVM. This means that your code will have fewer bugs because there won't be any unexpected runtime errors due to mismatched types.
3) Null Safety - Null safety is one of Kotlin's most powerful features because it prevents null pointer exceptions from happening at runtime by ensuring that all variables cannot be null unless explicitly declared so using.
Is Kotlin better than Java?
Is Kotlin better than Java? It is a common question that comes up when you get to know about Kotlin. Developers are trying this new language in the hope that it makes their life easier.
Kotlin was named Language of the Year for 2016 by Programming Language of the Year Awards, and in 2017 by TIOBE Programming Community Index.
