A free, open-source ebook (in Japanese, with Chinese and Korean translations) teaching JavaScript Promises and async functions, written in AsciiDoc and published as HTML and PDF. The repository contains the book source, build tooling, and runnable example code.
Use cases
- learn how JavaScript Promises work
- understand Promise.all, Promise.race, then/catch patterns
- learn async/await and how it relates to Promises
- find examples of testing Promise-based code with Mocha
- download a free PDF reference on JavaScript async programming
- contribute to or translate an open-source programming book
When to choose
- you want a concise, free introduction to JavaScript Promises and async functions
- you prefer learning from a book with runnable, tested example code
- you need a reference you can read offline as PDF or on mobile via the web version
When to avoid
- you need comprehensive coverage of all JavaScript topics rather than just Promises
