ParadigmPrimarily imperative and procedural, with some support for object-oriented and functional programming.Functional-first, with strong emphasis on immutability and pure functions.
TypingDynamically typed.Statically typed with type inference.
PerformanceVery fast and lightweight, suitable for embedded systems and scripting.Runs on WebAssembly, offering good performance for web applications, but generally slower than native code.
Libraries and frameworksRich ecosystem for game development (e.g., Love2D, Corona SDK) and scripting, but fewer general-purpose libraries.Smaller ecosystem, focused on WebAssembly and functional programming, with limited libraries compared to mainstream languages.
Community and supportLarge, mature community with extensive documentation and support.Small and emerging community, with growing but limited resources and support.
Learning curveGentle learning curve, easy for beginners.Moderate learning curve, especially for those new to functional programming.
