Differences Between Groovy vs Kotlin
What is Groovy?
Many of Groovy’s strength lies in its AST transformations, triggered by annotations. After version 2, Groovy can be compiled statically, allowing model inference furthermore performance near that of Java. Groovy 2.4 remained the latest significant release following Pivotal Software’s sponsorship which ended in March 2015. Groovy 2.5.2 is the developed durable version of Groovy. Groovy has since improved its governance structure to a Project Management Committee in the Apache Software Foundation. Features of Groovy support both static and dynamic typing, operator overloading, the Native syntax for lists including associative arrays, Native support for regular expressions, and several markup languages such as XML and HTML. Groovy is manageable for Java developers after the syntax for Java and Groovy are quite comparable. You can handle existing Java libraries also possible to extend the java.lang.Object.re
What is Kotlin?

Key Differences Between Groovy and Kotlin
Both are approved choices in the industry. Let us consider some of the notable difference:
- Considering Groovy was created as a dynamic language, also @Compile Static, while a comprehensive annotation, was attached following. Its characteristic seems a little bolted on; moreover, it does not enforce people to code in a static way. It’s not applicable everywhere. However, sometimes even with it on, Groovy appears to have some unique dynamic performance every now and then. Kotlin is 100% Static; furthermore, the dynamic is not an option. Kotlin designed as a statically typed language, including a great type system plus additional statically typed language advantages. Groovy – in the initial position is a dynamically typed language, also simply then – statically.
- Meanwhile, when you allow compiling static in groovy, you get plainly Java. On another side – Kotlin, in their type-system, possess two types of references: nullable and non-nullable, so you can compose code by limited NPEs.
- The next exceptional peculiarity of Kotlin – it doesn’t do any implicit conversions, on the other hands – groovy implicitly convert double to big decimal and so on.
- Although Kotlin has a lot of other characteristics, like smart casts, ADT (doc), type-safe builders, zero-cost abstractions and finally, great IDE support.
- Furthermore, Kotlin type-inference work’s like a charm, without any annotations in every piece of language than Groovy’s.
- Ternary operator: Both, Kotlin vs Groovy provide Elvis operator; however, the ternary operator is missing from the latter.
Groovy vs Kotlin Comparison Table
Below is the topmost comparisons:
|The basis of comparison||Groovy||Kotlin|
|Definition||Groovy is an object-oriented programming language for Java Virtual Machines. It is used to connect Java modules, to write Java application moreover to enlarge existing Java application.||Kotlin is an open-source programming language that connects object-oriented programming features like Range Expression, Extension Function, Companion Object, Smart casts; moreover, Data classes are considered to be a surplus of the Kotlin Language.|
|Data Class||Groovy 1.8 introduced a few new alterations, which involve @ToString and @EqualsAndHashCode. These annotations can be applied to implement a few related characteristics provided in a Kotlin data class.||A class can be labeled as a data class. The standard functionality and utility functions are already existing in these data classes.|

|Popular websites that use technology||Netflix, Cisco, LinkedIn, Sony, Oracle, Nestle, MasterCard, MTV, IBM||Pinterest, Uber, Cradle, Ever note, Corda, Coursera, Pivotal, Atlassian.|
Conclusively, it’s a summary of the relationship between Kotlin vs Groovy. The community has a significant impact when it comes to new highlights, and there’s always to assume that a Scala feature will become part of future Java. Notwithstanding their differences, they are total interoperable, which indicates they can co-exist in the same application. Both, Kotlin vs Groovy are JVM languages and are developer-friendly.
