Key differences between Elm and Carbon

CharacteristicElmCarbon
SyntaxClean, functional, Haskell-inspired syntax with significant whitespace and no semicolons.C++-like syntax designed for familiarity to C++ developers, with modern enhancements.
ParadigmPurely functional, declarative, and focused on immutability.Multi-paradigm, primarily imperative and object-oriented, with support for generic programming.
TypingStatically typed with strong type inference and no null or runtime exceptions.Statically typed with a focus on safety and interoperability with C++.
PerformanceCompiles to efficient JavaScript for web applications; performance is good for UI but not suitable for system-level tasks.Aims for high performance comparable to C++, suitable for system-level and performance-critical applications.
Libraries and frameworksSmaller ecosystem focused on web development, with a curated package repository.Ecosystem is nascent; aims for compatibility with C++ libraries and tools.
Community and supportSmall but active community, mainly in web development; official support and resources are limited.Very early-stage community, mostly experimental, with backing from Google and some open-source contributors.
Learning curveSteep for those new to functional programming, but simplified by helpful compiler messages.Designed to be approachable for C++ developers; learning curve depends on familiarity with C++ concepts.
