Why is Kotlin Better than Java?

Clean & Safe Code

Kotlin follows simplistic syntax, making the code readable and easy to manage. It is reasonably easy to learn when it comes to syntax. And this makes it a better choice than Java’s complex and hard-to-remember syntax. Moreover, Kotlin comes with many security features that make the codebase safe and protect it from issues.

Allows Functional Programming

Kotlin allows functional programming. That makes working with it significantly easier. With Kotlin’s functional programming features, you can reuse the same code for multiple things and use higher-order functions. Resulting in fully functional, performing mobile and web apps.

Supports Coroutines

Coroutines are new function types that can be executed and stopped as and when required. And these Coroutines don’t require uninterrupted execution, and Kotlin has this feature. This makes space for interrupting heavy workloads and restarting them without losing the progress. Considerably speeding your overall app development process.
