What is Ruby? The Shining Gem of Modern Programming

The credit for developing Ruby, an open-source object-oriented programming language, goes to Yukihiro Matsumoto. Yukihiro intended to build a scripting language that took the use of object-oriented programming and allowed for more code reuse in order to speed up development.

A scripting language, unlike C and C++, does not communicate directly with the hardware. It's written to a text file, then an interpreter processes it and converts it to code. The majority of these programs are procedural in nature, which means they are read from top to bottom.

Object-oriented programming languages, on the other hand, separate code into objects that may be generated and used as needed. These objects can be reused in other areas of the program or even in different apps.

What is Ruby?

Ruby is a programming language that is intended to increase programmer efficiency while still being enjoyable. Ruby is popular among programmers because it is high-level and has straightforward syntax. Due to Ruby's high level and abstract nature, it is a simple language to learn and apply.

While many low-level languages need hundreds of lines of code to do even the simplest task, Ruby allows you to create your first cloud application in only a few hours. It's also an excellent alternative for swiftly developing apps, and it outperforms Python when it comes to web development.

Therefore using Ruby, you'll be able to focus on finding a solution to your problem since you'll be writing less code.

Why should you use Ruby?

5 features of Ruby

Ruby has different naming standards for variables, methods, constants, and classes.

Constant: Constants start off with a capital letter

Global variable: To define a variable as a global variable, it needs to start with the $ symbol

Instance variable: To define a variable as an instance variable, it needs to start with the @ symbol

Class variable: To define a variable as a class variable, it needs to start with the @@ symbol

Method: You are allowed to begin the name of a method with a capital letter

Naming conventions

Ruby is a completely pure object-oriented programming language. Every value is a distinct object. A class is assigned to each object, and each class has a superclass. Each code has its own set of characteristics and actions. Ruby has been influenced by the Smalltalk programming language. The rules that apply to objects apply to all of Ruby.

Object-oriented

There are about 42 keywords in Ruby that can't be used for anything else this also includes the naming of classes and variables. Therefore, keywords are also known as reserved words.

Keywords

Ruby is very particular when it comes to cases, i.e, uppercase and lowercase letters are treated as entirely different from one another. Therefore, Ruby is a case-sensitive language.

Case sensitive

In Ruby, a constant is similar to a variable, except that its value is expected to remain constant throughout the program. The Ruby interpreter does not enforce constant consistency, although it does send a warning if a program modifies a constant's value. Constants have the same lexical structure as local variables, with the exception that they start with a capital letter.

Variable constants

Ruby on Rails is an open-source framework for writing web applications that are built on top of Ruby by providing Ruby developers with a faster, more efficient way to write code. It is essentially a collection of code libraries that provide a ready-to-use solution for common website chores like creating tables, forms, and menus. It is technically described as a RubyGem package library that can be installed using the operating system's command-line interface.

In order to create web programs that run on a web server, it integrates Ruby with JavaScript, HTML, and CSS. Since Ruby on Rails operates directly on the web server, it is considered a back-end or server-side web application development platform.

In the next section, let me walk you through a comparison between Ruby and Ruby on Rails. This will help you crack Ruby on Rails developer job interviews.

What is Ruby on Rails?

Ruby is an object-oriented general-purpose programming language that is free to use, and Ruby on Rails is a free web development framework.

Ruby vs Ruby on Rails

Ruby is most commonly used to create web apps, as we've already established. However, because it is a general-purpose language, it may be used for a wide range of applications.

Popular websites such as Airbnb, Hulu, and MyFitness Pal have all used Ruby to propel themselves. This one fact alone demonstrates Ruby's versatility and strength.

Ruby is also used to create static websites. All web pages on a static website are loaded at the same time. This increases webpage loading times and makes website setup quick and simple.

Another obvious use for Ruby is web servers. Puma, Unicorn, and Passenger are examples of existing Ruby-based web servers.

What are the applications of Ruby?

People frequently compare Ruby's characteristics to those of other programming languages when deciding which programming language to learn or adopt for a project. But arguably the most frequently compared language to Ruby is Python, as both of them can be used for many of the same purposes. Due to Python and Ruby being so similar, it can be difficult for new programmers to determine which language to learn.

Ruby vs Python

Both are high-level server-side scripting languages

Both may be used for web apps and are cross-platform compatible

Both Ruby and Python may be used in GNU Debugger (gdb) styles and are supported by Emacs modes

Both employ IRB, an interactive prompt, and both languages objects are robustly and dynamically typed

Both Python and Ruby feature simple, easy-to-read syntax

Similarities between Ruby and Python

Differences between Ruby and Python

What is Ruby? An open-source programming language that has been major strides in the coding space since its inception about three decades ago. Ruby is still popular among programmers because it is high-level and has straightforward syntax. While many low-level languages need hundreds of lines of code to do even the simplest task, Ruby allows you to create your first cloud application in only a few hours.

Now, you know what exactly Ruby is and how versatile and useful it is for your web development career. A shining gem, among the giants of modern programming languages, Ruby is something exceptional. A simple scripting language that originated almost three decades ago, is still going strong and stronger than ever, with its applications ranging far and wide.

In this article, we will be discussing Ruby, its features,  applications, and whether or not you should use it. This will help you land the best Ruby developer jobs. So, let us dive in, to learn more about this shining gem of modern programming, Ruby.

Since its inception, Ruby has had 14 released versions:

Absolutely. Ruby is still a Top 20 language on all ranking indices. Ruby was chosen by 8.4% of respondents at StackOverflow Developer Survey for “Most Popular” technology.

Ruby JIT allows an interpreted language such as Ruby to optimize frequently run methods so they run faster for future calls.
