RUBY : Programming language: Overview
Ruby is a dynamic, object-oriented programming language that is designed to be simple and easy to read and write. It was created by Yukihiro Matsumoto in the mid-1990s and has since gained popularity as a general-purpose language that can be used for web development, software development, and scripting.
Here are some key features and characteristics of Ruby:
1. Object-oriented: Everything in Ruby is an object, including classes and methods.
2. Dynamic: Ruby is a dynamic language, meaning that variables do not need to be declared before use, and their type can change at runtime.
3. Concise syntax: Ruby's syntax is designed to be concise and readable, using keywords and symbols that are easy to understand.
4. Metaprogramming: Ruby allows for metaprogramming, meaning that programs can write other programs.
5. Open-source: Ruby is open-source software, meaning that the source code is freely available to anyone to use, modify, and distribute.
6. Web development: Ruby on Rails is a popular web development framework built on top of Ruby, used to build dynamic and scalable web applications.
Overall, Ruby is a flexible and expressive language that can be used for a wide range of applications, from scripting to web development to software development. Its focus on readability and ease of use make it a popular choice among developers, and its open-source nature has contributed to a large and active community of developers who contribute to its development and use.
