Groovy vs JRuby: What are the differences?
## Key Differences Between Groovy and JRuby
<Write Introduction here>
1. **Syntax**: Groovy follows a more Java-like syntax, making it easier for Java developers to transition, whereas JRuby uses Ruby syntax, which may be more familiar to developers coming from a Ruby background.
2. **Static Typing**: Groovy supports static typing if required, but it also allows dynamic typing, providing flexibility, while JRuby is dynamically typed, which can be advantageous for rapid development but may lead to potential errors at runtime.
3. **Concurrency**: Groovy lacks strong support for concurrency, making it less suitable for intensive multi-threaded applications, whereas JRuby leverages the powerful concurrency capabilities of the JVM, making it a better choice for highly concurrent applications.
4. **Performance**: JRuby generally outperforms Groovy in terms of raw performance, especially when dealing with computationally intensive tasks, due to its ability to take advantage of the JVM's optimizations and Just-In-Time compilation.
5. **Community and Ecosystem**: The Groovy community has a strong presence in the Java ecosystem, with numerous libraries and frameworks available, while JRuby benefits from the vibrant Ruby community and a rich ecosystem of Ruby gems and libraries, providing different sets of tools and resources for developers.
6. **Compatibility**: Groovy is designed to seamlessly integrate with Java code, allowing developers to freely mix Groovy and Java within the same project, whereas JRuby enables Ruby code to interact with Java code through Java Native Interface (JNI), offering a different approach to interoperability between the two languages.
In Summary, Groovy and JRuby have key differences in syntax, static typing, concurrency support, performance, community ecosystems, and compatibility with Java, providing developers with distinct choices based on their preferences and project requirements.

What is Groovy?
It is a powerful multi-faceted programming language for the JVM platform. It supports a spectrum of programming styles incorporating features from dynamic languages such as optional and duck typing, but also static compilation and static type checking at levels similar to or greater than Java through its extensible static type checker. It aims to greatly increase developer productivity with many powerful features but also a concise, familiar and easy to learn syntax.
What is JRuby?
JRuby is the effort to recreate the Ruby (http://www.ruby-lang.org) interpreter in Java. The Java version is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application. See the docs directory for more information.

What are some alternatives to Groovy and JRuby?
Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Scala
Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.
Kotlin
Kotlin is a statically typed programming language for the JVM, Android and the browser, 100% interoperable with Java
Python
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
Gradle
Gradle is a build tool with a focus on build automation and support for multi-language development. If you are building, testing, publishing, and deploying software on any platform, Gradle offers a flexible model that can support the entire development lifecycle from compiling and packaging code to publishing web sites.
