The JavaScript Minefield
When I was starting out as a programmer, I learned and worked in C++. There weren’t that many options for Mac OS 7 development at the time. I had a copy of MetroWorks CodeWarrior.

そこそこユーザビリティの高いフォームを作った
そこそこユーザビリティの高いフォームを作った 入力内容の検証とか、郵便番号変換を備えた、そこそこ使いやすいフォームのテンプレートを作りました time2014/01/18 hatenabookmark- 去年末実家に帰省していた時に、jQueryの練習＆業務で使うために、フォームバリデーションとか郵便番号変換とかを備えた、そこそこユーザビリティの高い入力フォームをコーディングしていたので、ここで公開しておきます。 フォームサンプル ソースお持ち帰り用 (Github) ここで"そこそこ"と言っているのは、もともと業務でユーザビリティ改善案として使うことが目的であって、ベストを目指してもサーバ制約やコスト的な観点で使えないことがあるから、そこは目指さないよという意味です。そもそも、フォームは必要悪ですし、ベストはフォームが存在しないことですね。 フロントエンド実装だけです（サーバ側スクリプト

Introduction to Promises in JavaScript
Callback Hell Callbacks are frequently used in both Node.js and client-side JavaScript to implement an asynchronous program flow. Perhaps the most common usages are jQuery’s AJAX callbacks, such as: $.get('http://my-url', function(data) { // this function will be invoked // at some point in the future // once the ajax request // has completed successfully. }); Things get more complicated once mult
