@babel/plugin-syntax-function-sent

What is @babel/plugin-syntax-function-sent?

@babel/plugin-syntax-function-sent is a Babel plugin that allows parsing of the `function.sent` meta-property in generator functions. This meta-property is used to access the value sent to the generator by the `next` method.

What are @babel/plugin-syntax-function-sent's main functionalities?

Parsing function.sent

This feature allows the generator function to access the value sent to it via the `next` method using the `function.sent` meta-property. This can be useful for handling values passed into the generator at different stages of its execution.

function* generator() {
  console.log(function.sent);
  yield;
}
const gen = generator();
gen.next('first'); // Logs: 'first'
gen.next('second'); // Logs: 'second'
