modulejs

At ~2kB minified, modulejs adds almost no overhead, making it ideal for performance-conscious projects where bundle size is critical, as highlighted in the README.

Modules automatically resolve and inject dependencies before instantiation, simplifying code organization and ensuring proper load order without manual intervention.

The API mirrors RequireJS, reducing the learning curve for developers already experienced with AMD patterns, as noted in the features.

Supports mock dependency injection via modulejs.require(id, mocks), enabling straightforward unit testing without external libraries, as demonstrated in the API examples.

Utilities like modulejs.state() and modulejs.log() provide clear visibility into module dependencies and instantiation status, aiding in debugging and dependency tree analysis.
