Key differences between Ruby and JavaScript

CharacteristicRubyJavaScript
SyntaxRuby has a more flexible and concise syntax compared to JavaScript.JavaScript has a more rigid and verbose syntax compared to Ruby.
ParadigmRuby is a pure object-oriented language that follows the principle of 'everything is an object'.JavaScript is a multi-paradigm language that supports object-oriented, functional, and imperative programming styles.
TypingRuby is dynamically typed, meaning that variable types are determined at runtime.JavaScript is also dynamically typed, but it has some support for static typing through TypeScript.
PerformanceRuby is generally slower than JavaScript due to its interpreted nature and garbage collection.JavaScript is generally faster than Ruby due to its JIT compilation and event-driven architecture.
Libraries and frameworksRuby has a strong focus on web development and has popular frameworks like Ruby on Rails and Sinatra.JavaScript has a wide range of libraries and frameworks for both front-end and back-end development, including React, Angular, and Node.js.
Community and supportRuby has a smaller but dedicated community with a focus on open-source development.JavaScript has a massive and active community with a strong focus on collaboration and sharing knowledge.
Learning curveRuby has a relatively easy learning curve due to its simple syntax and focus on readability.JavaScript has a steeper learning curve due to its complex syntax and the need to understand various programming paradigms.
