should.js BDD Assertions

should.js is an expressive, BDD-style assertion library for JavaScript, designed to be framework-agnostic and provide helpful error messages. It is currently at version 13.2.3 and maintains an active release schedule with frequent patch and minor updates. A key differentiator is its default behavior of extending `Object.prototype` with a non-enumerable `should` getter, enabling `(value).should.be.something` syntax. For environments where `Object.prototype` extension is undesirable, it offers an alternative function-style API, `should(value).be.something`. The library ships with TypeScript type definitions, though specific import patterns have seen minor adjustments across versions. It aims for readability and clear test code.
