Usage

When writing parsers, .bind chains sometimes introduce a kind of Callback Hell. But fortunately, you can avoid it using generators to keep your code readable and maintainable!

For example, the following code

const parser =
  parserA.bind(x =>
    parserB.bind(y =>
      perserC.bind(z =>
        pure(foo(x, y, z))
      )
    )
  );

can be rewritten as

const parser = qo(function* () {
  const x = yield parserA;
  const y = yield parserB;
  const z = yield parserC;
  return foo(x, y, z);
});
