Experimentation is the name of the game in front-end JavaScript development, and reactive frameworks like Angular, React, Vue, and Svelte are the nexus for innovation in modern web UIs. Keeping an eye on that landscape helps keep your perspective fresh while ensuring you don’t miss out on important developments that could improve your workflow and the performance of your apps.

This month’s JavaScript Report has you covered, with both a comparison of the top frameworks and a closer look at the major new features in Angular 19. We’ll also dig into the React compiler (now in release candidate stage 1) and a collection of experimental features proposed for React. And you’ll get a glimpse at OXC, the new Rust-based JavaScript tool set from Evan Yu—creator of Vue and Vite, among other projects.

Catching up with Angular 19
Angular is in the midst of a drive to become more developer-friendly, more powerful, and faster than ever. Here’s a look at the major features in the latest release, including incremental hydration, improved server routes, better signals integration, and a performance-boosting engine refactor.

Comparing Angular, React, Vue, and Svelte
Keeping up with the big ideas emerging in front-end JavaScript framework design is almost a full-time job. This comparison has you covered with highlights from four of the best.

Is the React compiler ready for prime time?
React’s compiler has reached release candidate stage 1, bringing it closer to general availability. Now is a good time to get to know this important new player in the React ecosystem.

Why cubicles are a software development anti-pattern
Developers, including JavaScript developers, generally really don’t like cubicles—or should we say, “concentration-cancelling workspaces”?

The JavaScript Oxidation Compiler
If you like JavaScript, it’s a good idea to keep an eye on Evan Yu, creator of Vue and Vite. Now he’s up to something new, with a Rust-based JavaScript tool set built for speed. OXC is worth a look.

Detecting and mitigating an authorization bypass vulnerability in Next.js
Sonatype’s recently announced discovery of 18,000 open source malware packages in the software supply chain was a stark reminder that developers are a malware target, too. Now is a good time to secure your Next.js installation.

React view transitions and more
The React development team walks through several experimental features and improvements in this post, including a first look at the new view transitions API.
