How TypeScript became a GitHub leader

I Spent 2 Days Migrating to TypeScript So I Could Write JavaScript Anyway Congratulations! You've adopted TypeScript. Now you're writing JavaScript with commitment issues. Let me paint you a picture: your team had The Meeting. Someone said " type safety " while gesturing vaguely at a stack trace. Someone else mentioned " developer experience " after their third coffee. Everyone nodded like they understood what that meant. You migrated your codebase, spent two days fixing config files, added typescript to your dependencies, and updated your LinkedIn. Then you wrote this masterpiece: const data: any = await fetchUserData(); Chef's kiss. Beautiful. You've taken a language designed to catch bugs at compile time and told it "nah, surprise me at runtime." It's like buying a seatbelt and wearing it as a scarf. TypeScript's whole thing is preventing undefined is not a function from ruining your Thursday afternoon. But any is the " I trust the universe " button—and you're mashing it like it owes you money. The compiler isn't fooled. Your IDE isn't fooled. And t https://lnkd.in/gHBxucF2

GitHub just dropped its latest Octoverse report, and the numbers are wild. TypeScript officially passed Python and JavaScript as the #1 language, and honestly, it makes total sense. We’re seeing new AI-powered solutions everywhere: web, backend, mobile, and desktop apps built with TypeScript. Because of that, downloads for React (frontend), Express (backend), React Native (mobile), Electron (desktop), and other frameworks on NPM exploded in 2025. TypeScript’s rise to the top isn’t a coincidence. The JS/TS ecosystem already has the largest developer community, but typed languages make agent-assisted coding way more reliable, and nearly every modern framework scaffolds with TypeScript by default now. With so many projects written in TS, LLMs are being trained heavily on it. So naturally, the more AI you use, the more likely it is to give you TypeScript solutions back.

Everyone is so obsessed with TypeScript that they overlooked HCL suddenly appearing on the radar again. HCL (Hashicorp Configuration Language) is a flavor of YAML that powers infrastructure-as-code tools like OpenTofu and Terraform. While everyone is brushing up on their TypeScript skills, I say that Terraform will be the growing in demand skill. Once all of us devs get replaced by ChatGPT, someone will have to maintain all that cloud infrastructure powering the AIs.

Let's talk about something quite interesting in TypeScript - 'Indexed Access Types.' In TypeScript, 'Indexed Access Types' let us look up a type by indexing another type. This is similar to how we access a property on an object or an array at runtime. Let’s say we have an 'as const' object, and we want our types to stay perfectly in sync with the values inside it. That’s where 'Indexed Access Types' shine. This means if the original object changes, your derived types update automatically. You can even use 'keyof' with it to extract all possible value types or combine specific keys to build flexible unions. And yes, this is why 'as const' is so useful because it ensures those values are literal types, not widened ones like 'string.' If you try to access a key that doesn’t exist, TypeScript immediately warns you, giving you both type safety and consistency. So far, I talked about ' as const' objects in TypeScript. What if instead of an object, we have an ‘as const’ array? Using 'as const', this array becomes a 'readonly tuple,' and we can use 'Indexed Access Types' to extract types from it the same way we do with objects. We can get the type of a specific element by its index or even create a union type of all the values in the array. Here’s where it gets interesting. If we use 'number' as the index type, TypeScript interprets that as 'all numeric indices', effectively giving us a union of all the element types in the array. That means if our array changes or if elements are added or removed, the derived type automatically reflects those changes. This pattern is incredibly powerful for defining value-driven types that evolve with your code. In short, Indexed Access Types help you create types that truly evolve with your data. #TypeScript #JavaScript #Programming #Development #Coding #WebDevelopment

I spent three hours debugging a production bug yesterday. The fix? A single typo in a property name. JavaScript didn't care. It just returned undefined and kept running. TypeScript would've caught it before I hit commit. That's the whole story, really. JavaScript lets you move fast. Write whatever, run it, see what happens. Perfect for prototypes, small projects, getting ideas out of your head. TypeScript makes you slow down. Define your types. Tell the compiler what you're doing. It argues with you before your code ever runs. Sounds annoying until you're managing a 50,000 line codebase with five developers. Then that compiler arguing with you becomes your best friend. The catch: TypeScript has a learning curve. You'll spend time fighting with type definitions when you just want to ship. For a weekend project, that's overkill. But if you're building something meant to last, something other people will touch, something that needs to scale... TypeScript pays for itself in the bugs you never write. Not a religious debate. Just different tools for different jobs. The question isn't which one is better. It's which one fits what you're building right now.

🔥 Ready to Master the Modern Backend? 🔥 I'm thrilled to announce the launch of our new NestJS Backend Development Workshop Series!

GitHub’s latest Octoverse Report just dropped and the results are stunning. TypeScript has officially overtaken Python and JavaScript to become the #1 programming language on the platform. It’s not hard to see why. The surge of AI-powered applications across web, backend, mobile, and desktop platforms has fueled massive growth in the TypeScript ecosystem. Frameworks like React (frontend), Express (backend), React Native (mobile), and Electron (desktop) have all seen record-breaking download numbers on NPM throughout 2025. TypeScript’s dominance isn’t a coincidence. The JavaScript/TypeScript ecosystem already boasts the world’s largest developer community and with its strong typing, TypeScript enables far more reliable AI-assisted coding. Most modern frameworks now scaffold new projects in TypeScript by default. As more codebases adopt TypeScript, LLMs are increasingly trained on TS based projects. The result? The more developers use AI tools, the more likely those tools are to generate TypeScript-first solutions in return reinforcing the cycle of its rapid rise. 😇 #TypeScript #GitHubOctoverse #AIDevelopment #DeveloperCommunity #ProgrammingTrends #TechInnovation #OpenSource #InnovationInTech #DigitalTransformation #TechTrends2025 #FullStackDevelopment

Finally made my first open source contribution. This week, my first pull request to stdlib-js, one of the largest standard libraries for JavaScript and Node.js, was officially merged 🚀 The contribution: ✅ Refactored the example for someByRight to use @stdlib/random/array/randu for generating arrays. ✅ Fixed a linting issue (no-new-array) and simplified the code by replacing a loop with a single function call. ✅ Updated both the runnable example and the package README to stay consistent with project guidelines. It might look like a small change — but this PR taught me a lot about: Navigating a massive codebase with thousands of packages. Following strict linting, documentation, and test coverage rules. Writing examples that are concise and reproducible. Big thanks to the maintainers at stdlib-js for their guidance and for making open source beginner-friendly. Next goal: contribute to a core math or utils module. 🧠 If you’ve been wanting to start open source but don’t know where to begin — pick a small issue, read the contributing guide carefully, and just start.
