Ruby , an open-source, dynamic, high-level, interpreted programming language.
Ruby is an open-source, dynamic, high-level, interpreted programming language. It was created by Yukihiro “Matz” Matsumoto in the mid-1990s with the goal of making programming more fun and productive. Since then, Ruby has become one of the most popular programming languages in the world, with a large and active community of developers and enthusiasts.
What can Ruby be used for?
Ruby is a versatile programming language that can be used for a wide range of applications, from web development to scientific computing. Some of the most popular uses of Ruby include:
– Web Development: Ruby is particularly well-suited for web development, thanks in large part to its Ruby on Rails framework (discussed below). With Ruby, developers can easily build dynamic, database-driven web applications.
– Scripting: Ruby’s simple and readable syntax makes it an excellent choice for scripting tasks, such as automating system administration tasks or batch processing.
– Data Analysis: Ruby has a number of powerful data analysis libraries, such as Numo::NArray and Daru, which make it a popular choice for scientific computing and data analysis tasks.
– Games and Mobile Apps: Ruby can also be used for game development and mobile app development, thanks to the availability of frameworks such as Rubygame and RubyMotion.
Ruby on Rails
Ruby on Rails is a popular web application framework that is built on top of the Ruby programming language. It was created by David Heinemeier Hansson in 2004, and has since become one of the most widely used web development frameworks in the world. Ruby on Rails (often simply referred to as “Rails”) is designed to make it easy and quick to build web applications by following a set of conventions and best practices.
Some of the key features of Ruby on Rails include:
1.Model-View-Controller (MVC) Architecture: Ruby on Rails follows the MVC architecture pattern, which separates an application into three distinct components: the model (which represents the data), the view (which represents the user interface), and the controller (which handles the interactions between the model and the view).
2.Convention over Configuration: Ruby on Rails follows the principle of “convention over configuration,” which means that the framework makes assumptions about how an application is structured and how its components interact. This helps to reduce the amount of code that a developer needs to write, and speeds up the development process.
3.ActiveRecord: ActiveRecord is a powerful ORM (Object-Relational Mapping) library that is built into Ruby on Rails. It allows developers to work with databases using an object-oriented interface, rather than writing raw SQL queries.
4.Routing: Ruby on Rails provides a powerful and flexible routing system, which allows developers to map URLs to specific actions and controllers within an application.
Why should I learn Ruby?
