Characteristic	Gleam	CoffeeScript
Syntax	Statically typed, inspired by ML-family languages, concise and clear with significant whitespace.	Transpiles to JavaScript, uses Python-like indentation, more succinct than JavaScript, but less strict.
Paradigm	Functional, immutable by default, designed for reliability and concurrency.	Multi-paradigm, primarily imperative and object-oriented, supports functional patterns.
Typing	Statically typed with strong type inference.	Dynamically typed, inherits JavaScript's type system.
Performance	Compiles to efficient Erlang or JavaScript code, benefits from BEAM VM's concurrency.	Performance similar to JavaScript, as it compiles directly to JS.
Libraries and frameworks	Limited ecosystem, can use Erlang/Elixir libraries with some effort.	Access to the full JavaScript ecosystem, including Node.js and browser libraries.
Community and support	Small but growing community, active development, limited resources.	Mature but declining community, extensive legacy resources, less active development.
Learning curve	Moderate, especially for those new to functional programming or static typing.	Gentle for those familiar with JavaScript, easy to pick up due to concise syntax.
