Using JavaScript to fill localStorage to its maximum capacity
Using JavaScript to fill localStorage to its maximum capacity Earlier this week, I had to test how one web app I work on behaves when it tries to store some data in an already full localStorage. To do so, I wanted to find a way to programmatically fill localStorage to its maximum capacity using JavaScript. Knowing that the only way to detect when the localStorage is full is catching the QuotaExcee
pzuraq | Four Eras of JavaScript Frameworks
April 25, 2022 Four Eras of JavaScript Frameworks April 25, 2022 I started coding primarily in JavaScript back in 2012. I had built a PHP app for a local business from the ground up, a basic CMS and website, and they decided that they wanted to rewrite it and add a bunch of features. The manager of the project wanted me to use .NET, partially because it’s what he knew, but also because he wanted i
Why I avoid async/await
EDIT: I recently turned this article into a talk I gave at UtahJS 2023. It’s also partly a response to some of the reactions I got to this article. In many ways, I feel like I did a bit of a better job with my arguments there than here. Let me know what you think. Whatever your stance on async/await, I’d like to pitch to you on why, in my experience, async/await tends to make code more complicated
僕らを縛る Node.js という呪いについて
これ僕らの物語であり、僕と君の物語であるかもしれない。 数日前、友人が言った。「久しぶりに Rails を書いたけれど、Node.js の良さに敵わない」と。 その言葉に同意しながらも、他方で少し不思議に思う。 いつから僕らは Node.js しか使わなくなったのか。あれだけ話していた Rails などの多くの Web 技術にときめかなくなったのか。と。 もちろん、使えないというわけではない。寧ろ今現役で十分な活躍をしているフロントエンドの人間は、等しく皆「主役であるバックエンドのサブとして存在するフロントエンド」を経験してきている。 書こうと思えば書ける。だがその中で、敢えてフロントエンドとその技術を選んできた。 だけど今はどうだろう。フロントエンドエンジニアはもはや「JavaScript を扱うソフトウェアエンジニア」となり、一般的なバックエンドは勿論、Node.jsが一級市民として存
Replit — Comparing Code Editors: Ace, CodeMirror and Monaco
EngineeringInfrastructureAce, CodeMirror, and Monaco: A Comparison of the Code Editors You Use in the Browser I’ve been working on Replit for roughly six years now, and as the team has grown, I’ve focused on the IDE (what we call the workspace) portion of the product. Naturally, I was increasingly preoccupied with the code editor. While we’ve considered creating a code editor that meets our needs,
When a JavaScript WeakMap() Actually Came in Handy
Back when I was working on slide-element, I noticed an issue that would occur when I rapidly toggled an element open & closed. If the previous animation wasn’t allowed to finish, the new one would eventually get outta whack, clipping the content on subsequent animations. The Cause of the WeirdnessThis was happening because each time an animation was triggered, I was grabbing the current “raw” heig
Load Third-Party JavaScript | Articles | web.dev
If you've optimized your code, but your site still loads too slowly, it's probably the fault of third-party scripts. Third-party scripts provide a variety of useful features that make the web more dynamic, interactive, and interconnected. Some of them might even be crucial to your website's function or revenue stream. But using them is risky: They can slow down your site's performance. They can ca
JavaScript vs JavaScript. Fight!
With software development, we are often presented with alternative choices for libraries and tools that appear to accomplish the same sort of things. Each one will advertise its key advantages, and we attempt to weigh the pros and cons. Sometimes, the differentiators have less to do with what we are accomplishing and everything with how we accomplish it. In those cases, it isn't always as clear wh
