Elm vs Groovy: What are the differences?
What is Elm? A type inferred, functional reactive language that compiles to HTML, CSS, and JavaScript. Writing HTML apps is super easy with elm-lang/html. Not only does it render extremely fast, it also quietly guides you towards well-architected code.
What is Groovy? A dynamic language for the Java platform. Groovy builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk. It makes modern programming features available to Java developers with almost-zero learning curve.
Elm and Groovy can be categorized as "Languages" tools.
"Code stays clean" is the primary reason why developers consider Elm over the competitors, whereas "Java platform" was stated as the key factor in picking Groovy.
Elm and Groovy are both open source tools. Elm with 5.3K GitHub stars and 424 forks on GitHub appears to be more popular than Groovy with 1.49K GitHub stars and 414 GitHub forks.
Starbucks, PedidosYa, and AgoraPulse are some of the popular companies that use Groovy, whereas Elm is used by NoRedInk, Brilliant, and RolePoint. Groovy has a broader approval, being mentioned in 79 company stacks & 73 developers stacks; compared to Elm, which is listed in 27 company stacks and 35 developer stacks.
