seventh

What is seventh?

The 'seventh' npm package is a lightweight and versatile library for handling asynchronous operations in JavaScript. It provides utilities for working with promises, including promise creation, chaining, and control flow management. It aims to simplify asynchronous programming by offering a more intuitive and readable API.

What are seventh's main functionalities?

Promise Creation

This feature allows you to create resolved or rejected promises easily. In this example, a resolved promise is created with the value 'Hello, World!' and the value is logged to the console.

const seventh = require('seventh');

const promise = seventh.resolve('Hello, World!');
promise.then(console.log); // Output: Hello, World!

Promise Chaining

This feature demonstrates how to chain multiple promise handlers together. Each handler processes the value and passes it to the next handler in the chain.

const seventh = require('seventh');

seventh.resolve(1)
  .then(value => value + 1)
  .then(value => value * 2)
  .then(console.log); // Output: 4

Parallel Execution

This feature allows you to execute multiple promises in parallel and wait for all of them to complete. The 'seventh.all' method takes an array of promises and returns a single promise that resolves with an array of results.

const seventh = require('seventh');

const promises = [
  seventh.resolve(1),
  seventh.resolve(2),
  seventh.resolve(3)
];

seventh.all(promises).then(console.log); // Output: [1, 2, 3]

Timeout Handling

This feature demonstrates how to create a promise that resolves after a specified timeout. The 'seventh.resolveAfter' method takes a timeout duration and a value, and returns a promise that resolves with the value after the timeout.

const seventh = require('seventh');

const promise = seventh.resolveAfter(1000, 'Done');
promise.then(console.log); // Output after 1 second: Done

Other packages similar to seventh

bluebird

Bluebird is a fully-featured promise library with a focus on performance and additional features such as cancellation, iteration methods, and more. Compared to 'seventh', Bluebird offers a richer set of utilities and is widely used in the community.

q

Q is a promise library that provides a way to manage asynchronous operations. It offers features like deferred objects and a variety of utility methods for working with promises. Q is similar to 'seventh' but has a different API and additional features like progress notifications.

async

Async is a utility module that provides straightforward, powerful functions for working with asynchronous JavaScript. It includes methods for parallel, series, and waterfall execution of functions. While 'async' is not promise-based, it offers similar control flow management capabilities as 'seventh'.
