Key differences between JavaScript and Haskell

CharacteristicJavaScriptHaskell
SyntaxJavaScript has a C-like syntax with curly braces and semicolons.Haskell has a unique syntax that is based on mathematical notation and is more declarative.
ParadigmJavaScript supports multiple paradigms including object-oriented, imperative, and functional programming.Haskell is a purely functional programming language.
TypingJavaScript is dynamically typed.Haskell is statically typed.
PerformanceJavaScript is generally considered to have good performance.Haskell is known for its focus on correctness and expressiveness rather than performance.
Libraries and frameworksJavaScript has a wide range of libraries and frameworks available, making it suitable for various purposes.Haskell has a smaller ecosystem of libraries and frameworks compared to JavaScript, but it still has a decent collection.
Community and supportJavaScript has a large and active community with extensive support resources.Haskell has a smaller but dedicated community with active support channels.
Learning curveJavaScript has a relatively low learning curve, especially for beginners.Haskell has a steeper learning curve due to its unique concepts and functional programming paradigm.
