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. plugin exports a default plugin factory asserting Babel 7 compatibility
  2. plugin factory returns plugin descriptor with name syntax-async-generators
  3. manipulateOptions appends asyncGenerators to parser plugins list
  4. manipulateOptions preserves existing parser plugins when adding asyncGenerators
  5. configureParserOptions helper creates plugin instance and updates parserOpts
  6. hasAsyncGeneratorsSyntax accurately checks presence of asyncGenerators in parser options
