Since I haven’t fully grasped the Promise feature in ECMAScript6 (ES2015), which is part of the JavaScript standard specification, I’ve compiled articles that I often refer to for my own reference.

• JavaScript Promiseの本
• Promise - JavaScript | MDN
• あなたが読むべきJavaScript Promises - JSer.info
• Promiseについて - JS.next

For Promise in Node.js, please also check out this article.

• Node.jsエンジニアなら2014年内に知っておきたいPromise入門 | Tokyo Otaku Mode Blog

For now, that’s all.

I’d also like to compile commonly used patterns for my own reference.

That’s all from the Gemba.
