Key differences between Groovy and Kotlin

CharacteristicGroovyKotlin
SyntaxGroovy has a syntax similar to Java with additional features like closures and dynamic typing.Kotlin has a more concise and expressive syntax compared to Java and supports features like null safety and extension functions.
ParadigmGroovy is a dynamic language that supports both object-oriented and functional programming paradigms.Kotlin is a statically-typed language that supports both object-oriented and functional programming paradigms.
TypingGroovy is dynamically typed, allowing for flexible and concise code.Kotlin is statically typed, providing compile-time type safety and null safety.
PerformanceGroovy is slower than Java due to its dynamic nature and runtime metaprogramming.Kotlin has similar performance to Java as it compiles to JVM bytecode.
Libraries and frameworksGroovy has good integration with Java libraries and frameworks.Kotlin has good interoperability with Java libraries and frameworks and also provides its own set of libraries.
Community and supportGroovy has an active community and good support from its developers.Kotlin has a growing community and is backed by JetBrains, which provides strong support.
Learning curveGroovy has a relatively low learning curve for Java developers due to its similarity to Java.Kotlin has a moderate learning curve for Java developers, but its concise syntax and modern features make it easier to learn.
