Ruby is an open-source, interpreted, high-level and general purpose programming language. The language is much similar to Python and is used in building web applications. Since it is a general purpose programming language, it is also used in data analysis, prototyping and proof reading of the concepts. Rails web is a popular implementation of Ruby and is a development framework built with Ruby. 

Ruby is a dynamic programming language. It uses garbage collection and compiles “just-in-time”. It provides a platform for multiple programming paradigms that includes procedural, object-oriented programming and functional programming abilities. 

Ruby is object-oriented. Every value is considered as an object, that includes classes, instances. It may hold types that many other programming languages position as primitives, like integers, boolean and null. The variable will have references to objects. Every function in the program is considered as a method. Methods are called on objects. The object class includes the methods that are defined at the high level scope.  Object class is the superclass of every other class, and hence such methods are called on any object.The are global procedures since they are visible and accessible in all scopes. It supports dynamic dispatch with inheritance, mixins and singleton agile method like belonging to and defined for, a single inheritance instead of being defined on the class. Since Ruby does not allow multiple inheritance, mixins are used to import classes as modules. 

Ruby is known as a multi-paradigm programming language because it allows procedural programming, that is, defining functions or variables outside classes would make them a part of the root or self object. It also supports object-orientation that considers every value as an object or functional programming (having anonymous functions, closures and continuations); it also contains all statements that have values, and functions that return the last evaluation.  It supports introspection, reflection and metaprogramming and also supports the interpreter-based threads. It features dynamic typing since it is a dynamic programming language, and provides support for parametric polymorphism.  

Ruby language has easy structure and has similar structure to that of Pearl and also the semantics are much similar to Smalltalk. It differs hugely from Python.
