Key differences between JavaScript and Ruby

CharacteristicJavaScriptRuby
SyntaxJavaScript syntax is similar to C++ and Java, with curly braces and semicolons.Ruby syntax is more flexible and closer to natural language, with less emphasis on punctuation.
ParadigmJavaScript supports both object-oriented and functional programming paradigms.Ruby is primarily object-oriented, but also supports functional programming.
TypingJavaScript is dynamically typed, meaning that variable types are determined at runtime.Ruby is dynamically typed, meaning that variable types are determined at runtime.
PerformanceJavaScript is generally faster than Ruby, but slower than lower-level languages like C++.Ruby is slower than JavaScript, but faster than some other interpreted languages like Python.
Libraries and frameworksJavaScript has a wide range of libraries and frameworks, including React, Angular, and Node.js.Ruby has a smaller selection of libraries and frameworks, but includes popular options like Ruby on Rails.
Community and supportJavaScript has a large and active community, with many resources and forums available for support.Ruby also has a strong community, but is smaller than JavaScript's and may have fewer resources available.
Learning curveJavaScript has a moderate learning curve, with some complex concepts like closures and asynchronous programming.Ruby has a relatively easy learning curve, with a focus on simplicity and readability.
