Z
Z is a pattern matching library for JavaScript that evaluates variables against structural shapes, data types, and literal values to branch program execution conditionally. It functions as a functional programming utility designed to deconstruct arrays and objects into parts during conditional evaluation.
The library transforms human-friendly pattern matching syntax into optimized nested conditional statements during compilation or initialization phases, evaluating complex structural conditions and returning matching branch results directly as standard expression values. It inspects runtime data shapes, types, and literal values dynamically to ensure safe type narrowing across matched branches, and evaluates target objects against structural templates to extract inner values and execute corresponding handler functions. Additionally, it splits variable-length sequences into discrete head elements and remaining tail arrays to process collections recursively.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
