#717 — December 19, 2024
🎄 We’ve made it to the end of 2024! In this issue, we’re being reflective, leading with a few news items but then looking at what made 2024 special in the world of JavaScript, and covering some of the biggest things we linked to this year.
Then we’re on a Christmas break for two weeks and will be back in your inbox on Friday, January 10, 2025, — yes, we’re moving back to Fridays for 2025! We hope you have a Merry Christmas and a Happy New Year.

The State of JavaScript 2024 Results — We recently encouraged you to take the annual State of JavaScript survey; the results are now out. 14,015 folks took part and we get to see what language features folks are using, experiences with popular libraries, build tool popularity, AI preferences, popular podcasts, runtime usage, and perhaps controversially, how more JavaScript developers are using TypeScript than not. There’s a lot to dig through here.

🗓️ What Happened to JavaScript in 2024
The JavaScript world has had a busy 2024, as you’d expect for the world’s most used programming language (despite the threat of being split into two). We looked back over the year and remembered some things that occurred:
-
In February, the React team posted a mega ‘React Labs’ update which framed the whole of React’s year, explaining the goals of the React Compiler and the eventual React 19 release (which went stable this month).
-
Alternative JavaScript runtimes had a great 2024, particularly Bun which introduced Bun Shell, Windows support and the ability to compile and run native C from JavaScript. Deno had a big year too, with the release of Deno 2 which included stronger Node.js/npm compatibility and package management tooling. Other systems continuing to progress this year include Boa JS, QuickJS, and Porffor.
-
Over at TC39, lots of language proposals were advanced this year (and that’s just a sample – here’s some more!). The ES2025 future is bright.
Boost Semantic Search with MongoDB Atlas Vector Search — Create embeddings, index them, and run semantic queries—just follow the quick start tutorial.
MongoDB sponsor
-
Deno decided to take the JavaScript trademark fight to Oracle and formally filed a petition with the USPTO to cancel it. We hope to see some developments here in 2025, but Oracle are prepared to defend it.
-
Not content to merely work on an edge platform, JS runtime, and fight Oracle, Deno also unveiled JSR, a fresh attempt at providing a registry for JavaScript packages.
-
There were lots of big releases generally for major JavaScript projects including Svelte v5, Node.js v23.0, Astro 5.0, TypeScript 5.7, Vite 6.0, React Native 0.76, Next.js 15, React Router v7, Rspack 1.0, Vue.js 3.5, and Angular 19.
-
The OG of JavaScript libraries jQuery 4.0 went into beta too! We keep our fingers crossed for a jQuery 4.0 final release in 2025.. ;-)
🥇 Our Top Items of 2024
Next up is a walk through the top items we included in 2024, ordered by level of reader engagement. No editorial judgments here – these are the things you cared about most:
1. console.delight — By far our most popular link of the year with over 20,000 clicks(!) – but who doesn’t use and love console.log? This post showed us how in the browser console it’s not merely for printing plain text, but can be used to render things like SVGs and HTML.
Zach Saucier
2. JavaScript Visualized: Promise Execution — A well-diagrammed article coupled with an (optional) 8 minute video that went into how promises work under the hood. Hugely popular as most of Lydia’s content tends to be.
Lydia Hallie
WorkOS: Sell to Enterprises with a Few Lines of Code — The modern identity platform for B2B SaaS, offering flexible, easy-to-use APIs to integrate SSO, SCIM, and FGA in minutes instead of months.
WorkOS sponsor
3. Is htmx Just Another JavaScript Framework? — Despite being five years old, htmx has seen a surge in popularity in 2023 and 2024, partly due to framework fatigue, but also as its simple HTML-oriented approach to adding functionality to pages appeals to a diverse group of developers. v2.0 landed in June.
Alexander Petros
4. Ecma International Approves ECMAScript 2024: What’s New? — In June, the Ecma General Assembly approved the latest ECMAScript / JavaScript spec, officially making it a standard. As with ES2023, it was a reasonably small step forward, but Dr. Axel rounded up what was new.
Dr. Axel Rauschmayer
5. JavaScript’s ??= Operator: Default Values Made Simple — The ??= nullish coalescing assignment operator snuck into JavaScript a few years ago via ES2021 and has been broadly supported almost everywhere for ages. Trevor showed off how it can tighten up your assignments.
Trevor I. Lasn
6. Eloquent JavaScript: The Fourth Edition — Coming several years after the third edition, the latest version of what is, perhaps, the best ‘all rounder’ book for learning JavaScript arrived in March “adjusted to the realities of 2024 and generally touched up.”
Marijn Haverbeke
7. 33 JavaScript Concepts Every Developer Should Know — A curated collection of links to tutorials on 33 different areas it’s worth understanding well, including types, closures, equality, scope, and different engines.
Leonardo Maldonado
8. How Google Handles JavaScript In Its Indexing Process — At one point if you wanted Google to index your content it needed to be directly written in HTML and not dynamically rendered with JavaScript. Things have since changed, of course, but by how much?
Zecchini, Moore, Siddle, Ubl (Vercel)

Meticulous automatically creates & maintains E2E UI tests. Zero flakes. Used by Lattice, Bilt Rewards and others.

🤗 Many thanks for reading JavaScript Weekly in 2024, sending in your links, and generally supporting us. We look forward to seeing you again early next year. Remember, we’re moving back to Fridays (long term subscribers may remember we used to go out on Fridays for the first several years) so we’ll be back on Friday, January 10.

🗓️ 2024 年 JavaScript 发生了什么
正如您对世界上最常用的编程语言所期望的那样，JavaScript 世界度过了忙碌的 2024 年（尽管存在[被一分为二]的威胁）( https://javascriptweekly.com/link/163801/d076523b1d))。回顾这一年，我们想起了一些发生的事情：
-
二月份，React 团队发布了大型“React Labs”更新，其中框架了整个 React 的一年，解释了 React 编译器的目标和最终的目标React 19 版本（稳定 月）。
-
替代 JavaScript 运行时在 2024 年表现出色，特别是 Bun，它引入了 Bun Shell、[Windows 支持](https://javascriptweekly.com/link/163805/ d076523b1d）以及编译并运行本机 C 的能力JavaScript. Deno 也度过了重要的一年，Deno 2 的发布 其中包括更强的 Node.js/npm 兼容性和包管理工具。今年继续取得进展的其他系统包括 Boa JS、QuickJS 和 Porffor 。
-
在 TC39 上，今年提出了很多语言提案（这只是一个示例 - [这里还有更多！](https://javascriptweekly. com/link/163813/d076523b1d))。 ES2025 的未来是光明的。

-
Deno 决定向 Oracle 提起 JavaScript 商标之争，并正式向 USPTO 提交请愿书要求取消该商标 我们希望在 2025 年看到一些进展，但甲骨文已准备好捍卫它。
-
Deno 不满足于仅仅在边缘平台、JS 运行时上工作并对抗 Oracle，它还推出了 JSR，这是为 JavaScript 包提供注册表的全新尝试。
-
主要 JavaScript 项目通常有很多重大版本，包括 Svelte v5、Node.js v23.0, Astro 5.0、TypeScript 5.7、[Vite 6.0](https://javascriptweekly.com /link/163823/d076523b1d), React Native 0.76、Next.js 15、[React Router v7](https:// javascriptweekly.com/link/163826/d076523b1d), Rspack 1.0、Vue.js 3.5和[Angular 19](https:// javascriptweekly.com/link/163829/d076523b1d）。
-
JavaScript 库的 OG jQuery 4.0 也进入测试版！我们祈祷 jQuery 4.0 最终版本能在 2025 年发布..;-)
🥇 我们 2024 年的热门单品
接下来是我们在 2024 年收录的热门项目，按读者参与度排序。这里没有编辑评判——这些是你最关心的事情：
1. console.delight — 到目前为止我们年度最受欢迎的链接，点击次数超过 20,000 次(!) – 但是谁不使用并且不喜欢“console.log”？这篇文章向我们展示了如何在浏览器控制台中它不仅用于打印纯文本，还可以用于渲染 SVG 和 HTML 等内容。

3. htmx 只是另一个 JavaScript 框架吗？ — 尽管已有 5 年历史，[htmx](https://javascriptweekly.com/ link/163836/d076523b1d）在 2023 年和 2024 年人气激增，部分原因是框架疲劳，而且其简单的面向 HTML 的向页面添加功能的方法吸引了不同的开发人员群体。 v2.0 于六月登陆。
亚历山大·佩特罗斯
4. Ecma International 批准 ECMAScript 2024：有什么新变化？ — 6 月，Ecma 大会正式批准了最新的 ECMAScript / JavaScript 规范使其成为一个标准。与 ES2023 一样，这只是向前迈出了相当小的一步，但 Axel 博士总结了新内容。
