他言語経験者が知っておきたいTypeScriptのクラスの注意点 - KAKEHASHI Tech Blog
はじめに こんにちは、岩佐 幸翠(@kosui_me)です。カケハシで認証基盤・ライセンス基盤・組織階層基盤などのプラットフォームシステムを開発・運用する認証権限基盤チームのテックリードをしています。 TypeScriptのクラス構文は、一見するとJavaやC#などの言語と非常に似ていますが、その背景にあるJavaScriptの特性により、振る舞いに重要な違いが存在します。これらの違いを理解することは、これまでの経験を活かしつつ、TypeScriptで堅牢なアプリケーションを構築する上で非常に重要です。 本記事では、主にJavaやC#など、クラスベースの静的型付け言語に慣れ親しんだエンジニアの方々を対象に、TypeScriptでクラスを扱う際に特に留意すべきポイントを解説します。さらに、クラスを用いない関数型のアプローチについても触れ、TypeScriptにおけるドメインモデリングの多様な

Today we’re excited to announce the availability of TypeScript 4.3! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript by adding syntax for static types. Tools like the TypeScript compiler can just erase TypeScript syntax, leaving you with clean readable JavaScript that works anywhere. So what’s that syntax adding if it just gets erased away? Well, when you add t

It is no surprise then that these tools play a major role in security analysis and hardening of relevant binary code.

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However
Introduction Java Naming and Directory Interface (JNDI) is a Java API that allows clients to discover and look up data and objects via a name. These objects can be stored in different naming or directory services, such as Remote Method Invocation (RMI), Common Object Request Broker Architecture (CORBA), Lightweight Directory Access Protocol (LDAP), or Domain Name Service (DNS). In other words, JND

GitHub - endojs/Jessie: Tiny subset of JavaScript for ocap-safe universal mobile code
This document is an early draft. Comments appreciated! Thanks. Today, JavaScript is the pervasive representation for (somewhat) safe mobile code. For another representation to achieve universality quickly, it must be a subset of JavaScript, and so runs at least everywhere JavaScript runs. Whereas JSON is a simple universal representation for safe mobile data, Jessie is a simple universal represent
Implementing Private Fields for JavaScript – Mozilla Hacks - the Web developer blog
This post is cross-posted from Matthew Gaudet’s blog When implementing a language feature for JavaScript, an implementer must make decisions about how the language in the specification maps to the implementation. Sometimes this is fairly simple, where the specification and implementation can share much of the same terminology and algorithms. Other times, pressures in the implementation make it mor
Reading Time: 9 minutes Phil Karlton has famously said that the two hardest things in computer science are naming things and cache invalidation1. That’s still kinda true in front-end development. Naming stuff is hard, and so is changing a class name when your stylesheet is cached. For quite a few years, I’ve had a gist called “Tiny Rules for How to Name Stuff.” Which is what you think: little tiny
V8 Torque is a language that allows developers contributing to the V8 project to express changes in the VM by focusing on the intent of their changes to the VM, rather than preoccupying themselves with unrelated implementation details.
