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

Contract

  1. format formats plain JavaScript objects with sorted keys and newline indentation by default
  2. format produces compact single-line string representations without whitespace when min option is true
  3. format limits recursive property traversal to specified depth replacing deeper structures with [Object] when maxDepth is configured
  4. format handles Map and Set collections and circular references safely
  5. format supports custom plugin serializer hooks to format domain-specific data structures
