JavaScript/TypeScript Analyzer Early Access Program

Vite is both a development server and a build tool for TypeScript and JavaScript applications, with support for hot module replacement (HMR), which updates code without a full page reload

Introducing chain-validate, a chainable validation library designed for JavaScript and TypeScript. Reasons for its creation include: - Combining validation and sanitization in a single chain - Collecting all errors instead of stopping at the first one - Returning structured results without throwing errors - Having zero dependencies - Maintaining a tiny bundle size Here’s a quick example: import { v } from 'chain-validate'; const userSchema = v.object({ email: v.string().required().trim().lowercase().email(), age: v.number().optional().coerce().min(18), }); const result = userSchema.validate({ email: ' KENIL@EXAMPLE.COM ', age: '21', }); result.value comes back already cleaned and typed. You can find it on npm: https://lnkd.in/dQPR_BPG Documentation is available at: https://lnkd.in/d_cYEWWz Check out the GitHub repository: https://lnkd.in/dR92DFAy I would appreciate feedback from JavaScript and TypeScript developers who are currently using Zod, Yup, or Joi. #JavaScript #TypeScript #OpenSource #WebDevelopment #NodeJS

🚀 Day 2/30 – JavaScript Challenge LeetCode Problem: 2620 – Counter Today I learned about one of the most important concepts in JavaScript Closures. 🔹 Concept Explained: The inner function remembers the variable number even after the outer function has finished execution. This is called a closure. 🔹 Key Learnings: ✅ Closures help maintain state without global variables ✅ Useful in counters, ID generators, and real-world applications ✅ number++ returns the current value, then increments it #Leetcode #Day2 #JavaScript #Developers #Frontend

📌 Question for Knowledge & Discussion (JavaScript) Explain the concept of an infinite loop in JavaScript using: for(;;) Also discuss different ways to stop this loop without using the break statement. ⚠️ Note: This is a discussion-based question. Please try to solve it yourself before checking any external help. Looking forward to your answers and different approaches! 💡

TypeScript 6.0 Will Break Your Build (This Checklist Saved Me Hours For Upgrading 3 Projects) . . It was Friday 4 PM when I was working on a Node.js project upgrade to TypeScript 6.0. I upgraded the version in package.json. I thought it was my last change and reinstalled dependencies. When I ran the build, it started to fail with a bunch of errors in terminal. I went through the TypeScript 6.0 announcement in detail and created a series of checklist that helped me upgrade 2 more projects in very less time than it took me for the first one. Let me give you a trick that I used for other 2 projects: * Before you npm install typescript@latest, run this: npx tsc --showConfig | grep -E 'strict|types|rootDir|module|target' and compare to 5.9. * Then add "types": ["node"] (plus whatever your env needs) and set rootDir explicitly if outputs are nesting. Fixes the fs/process errors and path changes for most projects and often speeds builds 20-50%. I have added a full breakdown in my Medium article.

Fix Babel Loader Bindings Error Running into Babel loader bindings errors during development can be frustrating ⚠️. These issues usually arise due to version conflicts, dependency problems, or misconfigured build tools. Understanding the root cause can help you resolve the error quickly and keep your development workflow smooth. 🔗 https://lnkd.in/diP693v5 #JavaScript #NodeJS #Debugging #WebDevelopment

🧠 Day 2 of 21 days challenge JavaScript Closures 🤯 A function remembering its data even after execution is done. In simple words: Inner function can access outer function variables. Sounds simple… but super powerful 💥 Used in: • Counters • Private variables • React hooks 💤 For easy understanding : outer() returns a function inner() remembers the value of count 👉 this is called a closure This changed how I see JavaScript 🚀 #JavaScript #Closures #Frontend #React.js

Finished building my Notes App using vanilla JavaScript. This project was mainly focused on strengthening core JavaScript concepts by building UI features from scratch without frameworks. Features implemented: • Create notes • Edit notes • Delete notes • Search notes • Pin important notes • Date formatting • localStorage persistence Some things this project helped me understand better: • how user actions translate into DOM updates • separating application state from rendering logic • handling dynamic UI with event delegation • debugging small UI behaviors Working through these problems made me appreciate how much logic exists behind even simple interfaces. Code available on GitHub: https://lnkd.in/g-E72cxQ Next: continuing to strengthen JavaScript fundamentals before moving into React.

Day 65/100 – Starting with Node.js 🚀 Learned: What Node.js is and how it allows JavaScript to run outside the browser Basic idea of the Event Loop and how Node handles multiple requests efficiently Introduction to Express and how it simplifies backend development What stood out: Node.js doesn’t work like traditional synchronous systems. Instead of waiting, it handles tasks asynchronously using the event loop, making it fast and scalable. #NodeJS #BackendDevelopment #JavaScript #LearningInPublic #100DaysOfCode

TypeScript 6.0 just dropped and it's the last one you'll recognize 🚨 This isn't a regular release. TypeScript 6.0 is the final version built on JavaScript. ⚡ What's coming: TypeScript 7.0 is being rewritten from scratch in Go with native speed and multi-threading. Release expected in a few months. 💥 The big changes: • 𝘴𝘵𝘳𝘪𝘤𝘵: 𝘵𝘳𝘶𝘦 by default • 𝘮𝘰𝘥𝘶𝘭𝘦: 𝘦𝘴𝘯𝘦𝘹𝘵 by default • 𝘵𝘺𝘱𝘦𝘴: [] by default (add ["node"] explicitly) • ES5, AMD, UMD targets killed • --𝘣𝘢𝘴𝘦𝘜𝘳𝘭 and --𝘰𝘶𝘵𝘍𝘪𝘭𝘦 deprecated Most projects will break without adjustments. 🎯 What you need to do: Set "𝘵𝘺𝘱𝘦𝘴": ["𝘯𝘰𝘥𝘦"] in your tsconfig and check the migration guide. TypeScript 6.0 is the bridge to 7.0. Upgrade now before the native rewrite lands. #TypeScript #WebDev #JavaScript
