Bare Assert

bare-assert is a minimalist assertion library for JavaScript, designed to be lightweight and efficient. It provides fundamental assertion utilities like `ok`, `equal`, and `deepEqual`, suitable for testing or validating conditions in various JavaScript environments. The current stable version is 1.2.0, released in December 2025. This library is part of the broader Holepunchto 'bare' ecosystem, which focuses on small, modular JavaScript runtimes for desktop and mobile, suggesting an emphasis on performance and a reduced footprint. Its release cadence appears to be on an 'as-needed' basis, with updates roughly annually or semi-annually. A key differentiator is its 'bare-bones' philosophy, offering essential assertions without the extensive feature sets found in larger frameworks like Chai or Node.js's built-in `assert` module. It ships with TypeScript types, leveraging TypeScript's `asserts` keyword for enhanced type narrowing.
