State of JavaScript 2024
Let's take a second to consider something: 2024's top three front end framework were all launched over a decade ago. Now sure, all three have evolved a lot along the way, and the patterns of 2014 would seem downright antiquated today. But given the JavaScript ecosystems's reputation as a constantly-churning whirlwind of change, it can be nice to know that some things do remain constant. Speaking o
JXAでMacのちょっとしたブラウザ操作を自動化する - ローファイ日記
SmartHR Advent Calendar 2024、14日目の記事です。昨日のご担当は tnagatomi さんでした！ qiita.com 株式会社SmartHRのプロダクトエンジニア @udzura です。労務基本機能を開発するチームで働いています。 今日は最近知った JXA で、Macのちょっとしたブラウザ操作を自動化する例をご紹介します。 JXA とは？ Macにはマシン上の操作を自動化するためのフレームワークが同梱されています。 例えばAutomatorのようなアプリを使って仕事を自動化するのですが、 AppleScript という言語もよく知られていました。このスクリプト言語を用いて特定のアプリケーションやウィンドウを操作したり、システム設定などの変更を記述することができます。 以下は開いているFinderの最初のウィンドウをドックに格納するスクリプトです。 tell a
The Humble For Loop in JavaScript
The Humble For Loop in JavaScript By Martijn Faassen • 2024-12-11 • Tags: programming, javascript I've seen some programmers try to avoid the humble for loop at all costs, in favor of more functional abstractions. I'm going to argue that the for loop is sometimes simply the best option. That doesn't mean you should always use it -- far from it -- but it does mean you should give it due considerati

GitHub - drogus/jawsm: JavaScript to WASM compiler
I started this project while working on a stress testing tool called Crows that runs WebAssembly scenarios. At the moment it only supports code compiled from Rust to WASM. As much as I love writing Rust, I also know it's not a widely popular language and besides, small tests are often easier to write in interpreted languages. The problem is, running scripting languages on top of WASM is not ideal
GitHub - no-gravity/dqs.js: Easy DOM access
// Without dqs.js: country = document.querySelector('#country'); // With dqs.js: import { dqs } from './dqs.js'; country = dqs('#country'); // Without dqs.js: country = document.querySelector('#country'); countries = document.querySelectorAll('.country'); city = country.querySelector('#city'); cities = country.querySelectorAll('.city'); // With dqs.js: import * as dqs from './dqs.js'; country = dq
Why I’m skeptical of rewriting JavaScript tools in “faster” languages
I’ve written a lot of JavaScript. I like JavaScript. And more importantly, I’ve built up a set of skills in understanding, optimizing, and debugging JavaScript that I’m reluctant to give up on. So maybe it’s natural that I get a worried pit in my stomach over the current mania to rewrite every Node.js tool in a “faster” language like Rust, Zig, Go, etc. Don’t get me wrong – these languages are coo
