At under 200 lines of code, the core is easy to understand and debug, as highlighted in the README's features section, making it highly approachable for learning FRP concepts.

Uses curried functions for partial application, enhancing modularity and expressiveness, which allows for cleaner composition of streams compared to method-based libraries.

Encourages users to build custom FRP abstractions as separate modules, enabling tailored solutions without bloating the core, as demonstrated by the listed community modules.

Optimizes stream updates to occur only once when multiple dependencies change simultaneously, preventing superfluous recalculations in complex dataflows.

Conforms to the Fantasy Land monad specification and supports the transducer protocol, facilitating seamless integration with functional libraries like Ramda.
