Hello, JavaScript developers!

Welcome to this week's JavaScript news!

This week we will focus on: Oracle's trademark dispute with Deno, new JavaScript time objects are supported by browsers, Google Chrome updates, and some powerful developer tools.

Let's get started!

Oracle's trademark dispute with Deno Oracle's attempt to register a "JavaScript" trademark has caused controversy. Ryan Dahl, the creator of Node.js and Deno, has filed a petition to cancel the trademark, and he believes that JavaScript is an open standard and should not be controlled by Oracle. Brief Overview:

Oracle's position: Oracle updated its trademark application in 2019 using screenshots of Node.js (which they do not own). Ryan Dahl's argument: He believes that JavaScript is maintained by multiple companies and should be a shared open standard. Oracle's response: They proposed to dismiss the petition, believing that consumers would not regard JavaScript as a common term. This debate raises a broader question of whether an entity should control the widely used technical terminology. We will continue to pay attention to the developments!

JavaScript Time Object: Simplifying date and time processing New Temporal objects will replace the clumsy Date objects in JavaScript, making date and time management more reliable and precise. Key Features:

Time zone and calendar support: Unlike Date objects, Temporal objects support time zone and calendar in built-in. Built-in Method: Provides built-in methods for converting, comparing, and formatting dates and times. Accuracy: Temporal objects ensure consistent processing of time-sensitive data and internationalization. Experimental browser support: Currently in the experimental stage, some browsers have provided support. Better parsing: Temporal objects avoid parsing problems that plague Date objects, making them a stronger choice for developers.

Handling long-running tasks in JavaScript If your web pages are stuck while handling heavy tasks, you may be experiencing main thread blocking problems. The browser can only perform one task at a time, and if the task takes too long, other operations (such as clicking a button or screen update) will be delayed. Solution:

setTimeout() : Decompose the task into small pieces and let the event loop process it step by step. requestAnimationFrame() : used for animation, transferring heavy tasks to background threads. Web Workers: completely offload tasks to separate threads to keep the main UI thread responsive. Using these methods, you can efficiently handle JavaScript tasks, ensuring a smoother user experience.

React-exe: Instant execution React component React-exe is designed to execute React components on the fly, ideal for creating real-time code previews, interactive documents, or code sandboxes. Main features:

Real-time execution: Instant execution of React components, ideal for real-time code preview or interactive sandboxing. External dependencies: Seamlessly integrate external libraries such as Tailwind CSS and Framer Motion. Custom styles: Supports custom styles and Tailwind CSS.

Chrome's new mobile DOM method: moveBefore Chrome's latest DOM operation method moveBefore allows you to move DOM elements without destroying their state. importance:

Status Save: Usually, moving the DOM element will cause iframes, etc. to reload or lose focus, moveBefore solves this problem. Performance improvements: React is integrating this feature, which promises to bring a smoother web application experience.

JStack: Quickly build Next.js applications JStack is designed to build fast, lightweight, and end-to-end Next.js applications. It provides automatic type safety, automatic completion and seamless deployment to platforms such as Vercel and Cloudflare. Advantages of JStack:

High performance: built on frameworks such as Hono, Next.js, TypeScript, and excellent speed and reliability. Multi-platform deployment: It can be easily deployed to platforms such as Vercel, Cloudflare, or Netlify. End-to-end type safety: Provides top-notch TypeScript support with neat APIs and autocomplete capabilities. Serverless WebSockets: Add scalable real-time capabilities without infrastructure management.

Tools and version updates worth watching this week

pnpm 10.2: The latest version improves the execution of package installation scripts and fixes some issues. Turborepo 2.4: Improved monorepo management, added caching mechanism, and supported ESLint v9. tinygradient 2.0: A JavaScript library that creates custom color gradients. fuse.js 7.1: A fast, zero-dependency fuzzy search library. re2js: A safer and more efficient regular expression processing library.

Thanks for reading this week's JavaScript news and hope it helps you! Remember to share it with your developers and subscribe to the next issue notification! See you next week!
