Question - What are the most important features of Kotlin?
Answer -
The most popular features of kotlin are:
- Kotlin is Concise: Kotlin reduces the writing of the extra codes, making Kotlin more concise.
- Compact code: Kotlin is an OOPs-based programming language. Its code lines may be reduced by up to 40% compared to Java, making it an excellent choice for software development.
- Kotlin is Simple: Kotlin is a simple language to learn. When working with Kotlin, compiling the code is simple, resulting in improved performance for Android development. It also explains which types of data functions can be used throughout the code.
- Open Source: Kotlin is open source for Android, and it uses the JVM to combine the benefits of OOPs and functional programming.
- Null safety: Kotlin is null safety language. Kotlin aimed to eliminate the NullPointerException (null reference) from the code.
- A high number of extensions: Kotlin supports various extension functions and extension properties without modifying the code. It means that it can help to extend the functionality of classes without touching their code. Kotlin may support a variety of extension functions to help developers make existing code more appealing and wonderful.
- Full Java Interoperability: Kotlin provides full interoperability for Java code. Java code can utilize Kotlin code, and Kotlin code can use Java code. So, if you are familiar with OOPs programming and good in Java programming language, you can switch to Kotlin development easily. Also, if there are any Java-based applications, they can be used with Kotlin's environment.
- Smart Cast: Kotlin supports the smart cast technique. By using this technique, we can reduce the cost of an application while also improving its speed and performance. It technique uses typecasting or immutable data to manage the efficiency of programming. \
- Low Learning Curve: Many businesses prefer Kotlin because of its low adoption cost. Most significantly, it is simple for developers to learn, especially if they have programming experience.
- Compilation Time: Kotlin is faster and better than Java in terms of its performance and fast compilation time.
- Tools-friendly: Kotlin is Tools-friendly. You can build the Kotlin programs by using the command line as well as any of Java IDE.
