Groovy is a dynamic programming language that runs on the Java Virtual Machine (JVM). It is designed to be concise and easy to read, making it a popular choice for developers who want to write code quickly. Groovy supports both static and dynamic typing, allowing for flexibility in coding styles. It integrates seamlessly with Java, enabling developers to use existing Java libraries and frameworks. One of the key features of Groovy is its support for domain-specific languages (DSLs), which allows developers to create custom languages tailored to specific tasks. This capability enhances productivity and code clarity. Groovy is often used in web development, particularly with frameworks like Grails, and in scripting tasks within Java applications.
