JS Sample Files
JavaScript (.js) files contain client- or server-side code executed by JavaScript engines in browsers or Node.js. They support ES5–ESNext syntax, modules, and async patterns. Use sample .js files to validate bundling, minification, linting, and runtime behavior across environments.

# Compare output with SHA256 values listed above.Where is the machine-readable manifest?
Use the manifest when you need stable names, SHA256 values, and URLs for automation.
Use in code — curl, Python, Node, wget
Copy any snippet directly into scripts, test suites, or CI pipelines. All URLs are stable and publicly accessible with no auth required.

- Validate syntax-highlight pipelines and file-type detection.
- Test parser robustness for larger source samples.
- Confirm linting/formatting tools handle encoding correctly.
