    • Iterator.prototype.asIndexedPairs -> Iterator.prototype.indexed
    • AsyncIterator.prototype.asIndexedPairs -> AsyncIterator.prototype.indexed
  • Avoid exposing spec fiction %AsyncFromSyncIteratorPrototype% in AsyncIterator.from and Iterator.prototype.toAsync, proposal-iterator-helpers/182, proposal-iterator-helpers/202
  • Avoid unnecessary promise creation in %WrapForValidAsyncIteratorPrototype%.next, proposal-iterator-helpers/197
  • Do not validate value in %WrapForValid(Async)IteratorPrototype%.next, proposal-iterator-helpers/197 and proposal-iterator-helpers/205
  • Do not forward the parameter of .next / .return to an underlying iterator by the extended iterator protocol, a part of proposal-iterator-helpers/194
