What is a Groovy DSL?
There is a larger definition of a domain specific language, however in the context of Groovy code, a DSL is a way of creating APIs that leverages Groovy’s closures to create an easy way to build complex data. To understand how a DSL works, you must understand how closures work.

Why Groovy is called DSL?
c(d). DSL or Domain specific language is meant to simplify the code written in Groovy in such a way that it becomes easily understandable for the common user. So the above example shows the transformation of the programming language to meet the needs of a domain specific language.
Why Groovy is used in Jenkins?
Groovy is suitable for beginners and is a good choice for uniting teams’ scripts. It can be used to orchestrate your pipeline in Jenkins and it can glue different languages together meaning that teams in your project can be contributing in different languages.
What is Groovy FIle?

What is Groovy and why it is used?
Groovy is a Java enhancer because it provides greater flexibility and even introduces special features to applications (those that have already been developed can be improved or they can be made from scratch). Groovy is a Java-like syntax, but with the ease of more moldable languages like Python and Ruby.
Is Groovy and Java same?
Groovy is powerful, optionally typed and dynamic language to develop an application on Java Platform where its syntax is Java-like. Its typing discipline is strong, static, and dynamic. Groovy is a superset of Java which means Java program will run in Groovy environment but vice-versa may or may not be possible.
What’s wrong with Groovy?
What is wrong with Groovy!!!!??? The problem comes from the way Groovy manages dynamic typing and string interpolation.

How Groovy is used in Jenkins?
Is the Groovy DSL built on top of Java?
The Groovy DSL implementation is built on top of the existing Java-based DSL, but it additionally allows to use Groovy language features in your routes, particularly Closures acting as Processor, Expression, Predicate, or Aggregation Strategy.
What does it mean to have a domain specific language in Groovy?

What kind of programming features does Groovy have?
Although Groovy is mostly an object-oriented language, it also offers functional programming features. According to Groovy’s documentation: “Closures in Groovy work similar to a ‘method pointer’, enabling code to be written and run in a later point in time”.
How is Apache Groovy similar to Python and Smalltalk?
It is both a static and dynamic language with features similar to those of Python, Ruby, and Smalltalk. It can be used as both a programming language and a scripting language for the Java Platform, is compiled to Java virtual machine (JVM) bytecode, and interoperates seamlessly with other Java code and libraries.
