Key differences between Racket and Gleam

CharacteristicRacketGleam
SyntaxLisp-like, uses lots of parentheses, prefix notation, minimalistic and uniform.Erlang/ML-inspired, uses indentation and punctuation, more conventional and readable for those familiar with modern functional languages.
ParadigmMulti-paradigm, primarily functional but supports imperative and object-oriented styles.Purely functional, emphasizes immutability and pattern matching.
TypingDynamically typed (with optional static typing via Typed Racket).Statically typed with strong type inference.
PerformanceInterpreted or compiled to bytecode, generally slower than native languages.Compiles to Erlang BEAM bytecode, inherits Erlang's performance characteristics, suitable for concurrent and distributed systems.
Libraries and frameworksRich ecosystem, especially for language design, education, and scripting; many libraries available via Racket package manager.Smaller ecosystem, can use Erlang and Elixir libraries, but fewer native Gleam libraries.
Community and supportEstablished, active academic and educational community, good documentation and support.Growing but smaller community, active development, good documentation but less mature support.
Learning curveSteep for those unfamiliar with Lisp syntax, but excellent educational resources.Gentle for those familiar with functional programming, approachable syntax, but less beginner-focused material.
