Safe And Reliable

Kotlin is the safest language considering that it includes various security features for immutability and nullability. Additionally, Kotlin also checks the accuracy of the program, helping you avoid runtime crashes.

Functional & Object Oriented

Kotlin’s web framework provides coding availability for both functional & object oriented manners. This helps out developers to code high-order functions and give them more space to abstract innovative ideas.

Named Parameters

Our skilled app developers are experienced in passing parameters by name rather than an index. This particular approach is quite useful when a function owns multiple number of parameters.

Simultaneous modification of data and lack of synchronization causes errors in multi-thread applications. Our dedicated developers possess expertise in manipulating immutable objects and high-order functions.

Is Kotlin Better Than Java?

Due to the similar bytecode structure, Kotlin applications run as fast as Java. However, Kotlin’s support for inline function does make the difference and make code run faster.
