callbag-basics

At only 7kB, it's lightweight, and benchmarks show it outperforms libraries like xstream and RxJS in performance-critical scenarios.

Same operators like map and filter work for both reactive streams (e.g., DOM events) and iterable sequences (e.g., generators), simplifying code across paradigms.

Implemented entirely as utility functions with no monolithic core, allowing easy customization and avoidance of heavy dependencies.

Follows the callbag spec, enabling seamless integration with other callbag-compliant utilities and encouraging a modular ecosystem.
