- **Easy to learn the basics**.
- **Clean and Concise syntax**.
- **Interoperable with Java**(means each and every Java package or library or framework or API will work seamlessly with Kotlin), plus you might know how much big the Java ecosystem is.
- Provides **nullable and type safety**(means you don't need to write a whole try-catch block for catching null pointer exception because it can be handled safely, and type casting is also much safer).

- **Strong type inference**.
- **OOPS with added modern features**.
- **Functional programming(FP) is at its best**, it is used to write more **concise, cleaner and better code**, and if we mix OOP and FP in Kotlin, we can even make **very amazing DSLs**.
- **Excellent and extended Java standard library**.
- **Coroutines**(and **structured concurrency**).
- Wide range of apps can be made like **multiplatform mobile, android, desktop, full-stack web apps** and much more.
- Can also be compiled to JS and interop. with it, thus Kotlin uses existing JS APIs to make **frontend web apps**, there are plans that Kotlin will even work seamlessly with Node JS in future.
- **Most preferred language for Android development with first-class support by Google**.
- **We can make Kotlin Multi-platform Mobile(KMM) applications that run natively on Android and iOS**, by sharing common business logical code, leveraging existing APIs and keeping UI/UX native on each platform.
- **KMM is a SDK that can also be added to an existing Android app to make it cross-platform**.
- **High speed UI development with Jetpack Compose(for Android) and Compose Multiplatform(for Web and Desktop)**.
- Can be used for **data science and visualization, and deep or machine learning**.
- **Kernel for Kotlin can be added in the Jupyter notebook**.
- In Kotlin, even **primitive types have their own classes**, and you can even add your own methods to them using extension functions without doing any inheritance.
- Kotlin is **open-source and free to use**, and there are **many 3rd party libraries** for Kotlin.
- Kotlin can be added in any Java IDE(although, **IntelliJ IDEA is most preferred for Kotlin**).
- **Kotlin can be easily integrated and work parallelly with any existing Java ecosystem or project(s)**.
- Kotlin can interop. with C and Obj-C for iOS and other native app development(s), as Kotlin can be compiled to native binaries using LLVM, also special WebAssembly support will be soon added in Kotlin.
- Kotlin-Native and KMM plugin is available in Xcode IDE for making iOS apps using Kotlin.
- **Kotlin Coroutines are lightweight than Java Threads**.
- Kotlin **Coroutines are multi-platform**, means they can be used when you are **targeting JVM or JS or Native platforms using Kotlin**.
- **Kotlin can run as a script too**(that eventually replaces the need of bash or groovy-gradle scripts).
- **Kotlin has a big, friendly and helpful community**.
- Kotlin is **adopted by many major institutions and universities** as a course in their academics.
- Kotlin is also a suitable language for **learning programming fundamentals and competitive programming**.
- Writing code with Kotlin might feel like it is a scripting language, but it is a statically typed programming language.
