what is ruby ?

 Ruby is a high-level, dynamic, and object-oriented programming language that was first released in 1995 by Yukihiro "Matz" Matsumoto. Ruby is designed to be easy to read and write, with a syntax that emphasizes code readability and simplicity. Ruby is known for its flexibility and expressiveness, which allows developers to write code quickly and efficiently.

Ruby is used for a wide range of applications, including web development, software development, system administration, and automation. Ruby on Rails, a web application framework written in Ruby, has become particularly popular for building web applications due to its emphasis on convention over configuration, which allows developers to quickly build and deploy web applications.

Ruby code is interpreted at runtime, meaning that code is executed directly without first being compiled. Ruby also features dynamic typing, which means that the type of a variable can change dynamically as the code executes.

In addition to its core language features, Ruby has a large and active community of developers who have created many useful libraries and frameworks for building applications. Some popular Ruby libraries and frameworks include Ruby on Rails, Sinatra, and RSpec.

Overall, Ruby is a powerful and flexible programming language that is well-suited for a wide range of applications. Its simplicity, expressiveness, and ease of use have made it a popular choice among developers around the world.
