Overview
Grails is an extremely productive, open-source web application framework, based on the Groovy programming language. A dynamic language, Groovy offers attributes similar to programming languages like Ruby, Python, Perl, and Smalltalk. It is based on the OOPs (Object Oriented Programming) concept and is perfect for developing web applications that run consistently on the Java Virtual Machine (JVM). Groovy and Grails is one of the most widely accepted web frameworks as it allows you to write codes easily and combine new Java modules to the existing ones.
Software organizations like Disney, MTV, ESPN and Netflix, have developed their well-known products using Grails, giving added impetus to its rapid increase in popularity. The salary report by Indeed states that the salary of the Groovy on Grails developer ranges from $56,040 per year to $118,572 per year.
