Example​

JavaScript
function* generator() {
  console.log("Sent", function.sent);
  console.log("Yield", yield);
}

const iterator = generator();
iterator.next(1); // Logs "Sent 1"

Is compiled roughly to

JavaScript
let generator = _skipFirstGeneratorNext(function*() {
  const _functionSent = yield;
  console.log("Sent", _functionSent);
  console.log("Yield", yield);

const iterator = generator();
iterator.next(1); // Logs "Sent 1"
