@babel/plugin-proposal-function-sent

範例

JavaScript

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

const iterator = generator();
iterator.next(1); // Logs "Sent 1"
iterator.next(2); // Logs "Yield 2"

大致編譯為

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"
iterator.next(2); // Logs "Yield 2"
