Today, we’ve got some game-changing updates: Claude can now write and execute JavaScript, JavaScript's GitHub crown falls to Python, new Node.js releases, the JS0/JSSugar debate, and more.

Python Beats Javascript

Python has defeated JavaScript to become the most popular language on GitHub for the first time in a decade!

Why the shift?

• AI Projects on the Rise: Python’s popularity has soared thanks to machine learning and data science tools, like Jupyter notebooks.
• JavaScript Holds Strong: JavaScript still dominates code pushes, and TypeScript's adoption is booming, strengthening the ecosystem.
• No JavaScript Decline: It's more of an evolution, with developers leveraging the benefits of TypeScript for better code quality.

Claude AI Now Runs JavaScript

Exciting developments in AI tooling coming from Anthropic’s Claude AI!

• New Analysis Tool: Claude can now write and execute JavaScript in a sandboxed environment
• Real-time Processing: Enables complex data analysis and processing capabilities

Node.js Double Release: Stability Meets Speed

Node.js just dropped two exciting versions! Let’s break them down:

Node.js v22.11.0 (LTS - Jod)

• Long-Term Support: Stability and security assured until 2025, maintenance through 2027.
• Production-Ready: Ideal for those managing stable, long-lived applications.
• Focus on Reliability: Aimed at giving developers peace of mind for mission-critical environments.

Node.js v23.1.0 (Current)

• JSON Modules Go Stable: Easy handling of structured data, with fewer headaches.
• Import Attributes: More control over how modules load, making complex configurations simpler.
• MockTimers API: Streamlines testing by simulating timers like setTimeout, making tests more efficient.

The JavaScript Split: JS0 and JSSugar

Remember the idea of splitting JavaScript into JS0 and JSSugar? Well, here’s the latest from this month’s TC39 meeting:

Key updates:

• No Rollback: Existing features and proposals won’t be affected. Future enhancements, however, will be split accordingly.
• Syntax and Capability Division: JSSugar will host new syntax features, while JS0 will focus on core API capabilities.
• Tooling Standards: There’s even a proposal to form a team to standardize JavaScript tooling, setting guidelines for tools like Babel and webpack.

The community is buzzing with opinions, and this debate is far from over!

Tools & Releases You Should Know About

Let’s speed-run through some of the other big tool updates this week!

• Faker 9.1: It lets you generate realistic test data effortlessly, from names and dates to financial data, across 60+ locales. It’s ideal for developers needing quick sample data, and the guided console demo makes onboarding simple.

• Dependency Cruiser 16.5: It helps you visualize and manage your project’s dependencies seamlessly. It scans for rule violations and automatically generates dependency graphs, keeping your codebase organized and untangled.

• Yantra: This JavaScript engine for .NET Standard is now fully written in C#. It compiles JavaScript to .NET Assembly with full ES5/ES6 feature support, including async/await. This engine makes mixing JavaScript with .NET smoother than ever.

• Chakra UI v3 arrives with a complete performance overhaul and over 25 new components. With Panda CSS integration and semantic tokens, theme customization is now seamless, and dark mode has never been easier to manage. This redesign makes building beautiful, accessible interfaces more powerful and intuitive.

  And that's it for the seventh issue of "This Week in JavaScript"! Thanks for tuning in!
