Key differences between JavaScript and Gleam

CharacteristicJavaScriptGleam
SyntaxC-like, flexible, dynamic, and permissive with many ways to accomplish tasks.Inspired by ML-family languages, concise, strict, and statically structured.
ParadigmMulti-paradigm: supports functional, imperative, and object-oriented programming.Primarily functional, with strong emphasis on immutability and purity.
TypingDynamically typed, types are checked at runtime.Statically typed with strong type inference, types are checked at compile time.
PerformanceGenerally fast due to highly optimized engines (e.g., V8), but can be affected by dynamic typing.Compiles to Erlang BEAM or JavaScript, performance depends on target; benefits from BEAM's concurrency model.
Libraries and frameworksExtensive ecosystem with thousands of libraries and frameworks for all purposes.Smaller ecosystem, but can interoperate with Erlang/Elixir libraries when targeting BEAM.
Community and supportLarge, mature, and active global community with abundant resources and support.Small but growing community, less support and fewer resources compared to JavaScript.
Learning curveRelatively easy to start, but quirks and dynamic nature can make mastery challenging.Steeper learning curve due to functional paradigm and static typing, but simpler syntax can help.
