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. assert @babel/plugin-transform-duplicate-keys exports a Babel plugin factory function
  2. assert duplicate identifier keys in object literals are transformed to computed string property keys
  3. assert duplicate string literal keys and matching identifier keys are transformed to computed keys
  4. assert duplicate numeric literal keys and matching string keys are normalized and transformed to computed keys
  5. assert getter and setter properties with duplicate keys are transformed into computed getters or properties
  6. assert multiple successive duplicate keys in object literals and nested objects are all transformed into computed keys
  7. assert non-duplicate object properties remain untransformed standard properties
