In this digital era, we have numerous scripting languages and web development frameworks to employ for web development. Selecting the best one amongst these available frameworks for your development platform is the prime decision. From 2005, the interest in a programming language called Ruby hiked with Ruby on Rails web framework which is written in Ruby. With mounting usage of Ruby for websites, Rails is repeatedly being endorsed. To know whether to opt for the Rails framework, we must first understand the difference between Ruby and Ruby on Rails.
Ruby is a high level, interpreted language, designed by Yukihiro Matsumoto in the mid-1990s. It has the ability to run on various platforms like Mac OS, versions of UNIX, and Windows. While if we talk about RoR, it is an open source framework developed by Heinemeier Hansson in 2003. It is written in Ruby and can run on different platforms like Macintosh, Windows, and Linux. Let us examine in-depth these two technologies to avail a better understanding.

What is Ruby?
Ruby is an all-purpose programming language based on object-oriented notions. It is an elucidated language exercised to invent web applications at an elevated pace. Ruby is an open-source that is written in C language and is free. With a stable release 2.7.1, it is more composed and apparent, having a lucid sentence structure.
Its syntax is quite similar to Perl and its semantics are related to Smalltalk, but it varies significantly from Python. It supports manifold programming models, including object-oriented, functional, and procedural programming. To avail an analytical view on Ruby and Ruby on Rails, we must examine its characteristics individually.
Ruby is object-based, which means each value is an object, consisting of instances of types and classes that a lot of other languages delegate as primitives. Variables constantly seize references to the objects. Generally, Ruby seems to abide by the ‘Principle of Least Astonishment (POLA)’, which means that it must function in a way to diminish confusion for skilled users. To understand it, let us have a look at its features:
- Robust Typing and Duck Typing
Ruby is an exceptional open source scripting language, which turns out that their programs are not compiled. Rather, its classes, methods, and modules are stated and compiled when its code operates.
The variables in Ruby are effortlessly typed language, which determines that any variable can grasp any kind of object. While the method is called on the object, Ruby looks up at the name regardless of the type of that object. This is called duck typing. It can permit you to create the classes that can profess to be another class.
Ruby is known to be a flexible programming language as you can simply redefine, remove, or insert existing active parts to it. It grants its users to liberally modify its parts as they desire. Due to its easy and clean syntax, it allows any new Ruby on Rails developer to study it very easily and quickly.
Ruby is basically an object-based language. Each value is an object and these objects have a class. Its code has its actions and properties. Also, Ruby is greatly influenced by Smalltalk programming language. The rules applicable to the objects are also applicable to the entire Ruby.
- Variable Constants
Constants are not actually constant in Ruby. If any previously initialized constant will be altered in a script, it will merely activate a caution but will not close down your program.
- Method Names
Here, the methods are approved to end with a question mark (?) or an exclamation mark (!). By assembling, the methods that respond to questions end with a question mark, and the methods that show that the method can alter the state of the object end with an exclamation mark.
- Naming conventions
Ruby programming language designates some of its naming conventions for its method, variable, class, and constant.
Constant: It starts with a capital letter.
Method name: It is allowed to start with a capital letter.
Instance variable: It starts with a @ sign.
Global variable: It starts with a dollar sign.
Class variable: It starts with a @@ sign.
Ruby has a characteristic of a distinct inheritance. It contains modules as well as classes. A module encloses methods, but no cases. Alternatively, the module can be mixed into class, which inserts the method of the module to that class. It is somewhat related to inheritance but more flexible.
What is Ruby on Rails?
Ruby on Rails is one of the most popular web frameworks; built on a model view controller (MVC) pattern, supplying default structures for web service, database, and web pages. Rails is a server-side application framework, which is written in Ruby under MIT License. Moreover, the comparison on Ruby vs Ruby on Rails would entail their key characteristics. Theoretically, it is described as the package library known as RubyGem, which can be installed by utilizing the command line interface of an operating system.
- Convention over Configuration
Programming in RoR refrains configuration folders to spare reflection, conventions, and vigorous runtime extensions. The thought behind ‘Convention over Configuration’ is conveying value mechanically without any user involvement. Some of the software systems, consisting of Java web application frameworks, need multiple configuration files, all with numerous settings which becomes incredibly tedious.
This convention aspect amplifies productivity, as you do not require to allot time setting up configuration files. It saves your time that could have been spent on wondering about where the stuff enters and what names to allot.
- Easy Programming Language
- Active Record
Rails depend on a powerful library named Active Record, which makes it easy for developers to fabricate database interface queries. This happens because they write the query in Ruby language, which is automatically transformed into SQL query, which gets the output and recovers an object. This active record library can complete mostly every task; therefore, it is rare to form a query in SQL.
- MVC Architecture
Rails follow a model-view-controller architecture, which is the most extensively utilized web application architecture. With such a pattern, Rails splits codes of varied functions, namely data layer, presentation layer, and preserving a resource layer. Hence, the developers who know other frameworks having MVC patterns can avail ease in implementing RoR.
- Simple Testing Tool
Rails also render a unit testing setup named RSpec, which is easy to understand. Because it is simple Ruby, you can employ it to examine functions imparted in an application by independently calling them. It aids you to make sure that your application has been tested appropriately.
7 Difference Between Ruby and Ruby on Rails
One of the most popular programming languages, similar to Java or C, Ruby is an all-purpose language, best recommended for its advantages in web programming. On the contrary, Rails is the software library, which broadens Ruby language. Let us observe Ruby vs Ruby on Rails in detail:
|Basis||Ruby||Ruby on Rails|
