Contract

  1. getSideChannelMap creates a side channel map instance supporting set, get, has, delete, and assert methods
  2. side channel map stores and retrieves metadata for object keys without modifying the object itself
  3. side channel map stores and retrieves metadata for primitive keys such as strings, numbers, and symbols
  4. side channel map delete removes key-value associations and returns boolean status
  5. side channel map assert verifies key existence and throws TypeError when key is not present
