This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. isKeyword returns true for standard JavaScript reserved keywords including control flow, declaration, and literal keywords
  2. isKeyword returns true for JavaScript operator and expression keywords such as typeof, instanceof, void, delete, new, this, and in
  3. isKeyword returns false for regular non-reserved identifier names
  4. isKeyword returns false for uppercase or mixed-case variants of keywords because JavaScript keywords are case-sensitive
