@babel/plugin-proposal-function-sent

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

@babel/plugin-proposal-function-sent is a Babel plugin that allows you to use the `function.sent` meta-property within generator functions. This meta-property provides a way to access the value passed to the generator's `next` method, which can be useful for more advanced control flow within generator functions.

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

Accessing the value passed to the generator's next method

This feature allows you to access the value passed to the generator's `next` method using `function.sent`. In the example, the generator function logs the value received each time `next` is called.

function* generator() {
  let value = function.sent;
  while (true) {
    value = yield value;
    console.log('Received:', value);
  }
}

const gen = generator();
console.log(gen.next('First').value); // Logs: 'First'
console.log(gen.next('Second').value); // Logs: 'Second'

Other packages similar to @babel/plugin-proposal-function-sent

co

The `co` package is a generator-based control flow library for Node.js and the browser, which allows you to write asynchronous code in a synchronous manner using generators. Unlike @babel/plugin-proposal-function-sent, which focuses on the `function.sent` meta-property, `co` is more about managing asynchronous operations with generators.

redux-saga

The `redux-saga` package is a library that aims to make application side effects (e.g., asynchronous actions like data fetching) easier to manage, more efficient to execute, and better at handling failures. It uses generator functions to handle side effects in a Redux application. While it doesn't provide the `function.sent` meta-property, it leverages generators for complex control flows.
