TypeScript Arrays Tuples Enums

TypeScript was created to improve JavaScript by adding static types. And if you've been wanting to learn it, start here with this TS handbook. You'll learn about type annotations, type inference, the union and any types, objects, function params, type aliases, interfaces, and lots more. https://lnkd.in/eEwVi_ZE

TypeScript 6.0 is out and doubling down on being JavaScript with syntax for types. The release adds built-in Temporal types, better generic inference, and prepares for Go compiler rewrite. Read more: https://lnkd.in/eY6PU-WW #devnews #typescript

👩💻 We built this in bootcamp with a professor walking us through it. I then decided to rebuild and upgrade it alone. The original was vanilla JavaScript + the OMDB API. It worked, but it was guided every step of the way. ⚙️ This time I upgraded it to React & TypeScript figuring out on the way what to change and why. ✨ Additional features that I added: – Favourites saved directly on the same page via localStorage – TypeScript to keep the data handling clean and intentional Turns out the best challenge after finishing a bootcamp is going back and doing it again, without a safety net. 🔗 Link: https://lnkd.in/eSXMHEKv #developerjourney #react #typescript #javascript

🚀 Day 980 of #1000DaysOfCode ✨ TypeScript Union Types Handling multiple possible data types in JavaScript can quickly get messy. In today’s post, I’ve explained TypeScript Union Types in a simple and practical way, so you can safely work with variables that can hold more than one type. Union types allow you to define multiple possible types for a variable — making your code more flexible while still being type-safe. I’ve also covered how to properly narrow types, so you can avoid errors and write predictable logic in real-world applications. This is one of the most commonly used features in TypeScript and is extremely useful when dealing with APIs or dynamic data. If you’re working with TypeScript, mastering union types will make your code much cleaner and safer. 👇 Do you use union types often, or do you still rely on `any` in some cases? #Day980 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #TypeScript #CodingCommunity #Programming

Perfect for React developers! Includes hands-on demos and practical examples. 🔥 What you'll learn: Arrow function basics & syntax variations Parameters, braces, and implicit returns Real-world usage in JavaScript/React YouTube video link: https://lnkd.in/dcyUxbzi

Ever written explicit type annotations for simple literals like 'production' or 3000? 🤔 TypeScript 6.0 now infers these automatically! Previously, TypeScript would infer `string` for 'production' and `number` for 3000, forcing explicit annotations for precise types. With TypeScript 6.0's enhanced literal type inference, you get precise literal types automatically, reducing boilerplate while maintaining type safety. → No more verbose annotations for simple constants → Better autocomplete and type checking → Cleaner, more readable code What's your favorite TypeScript 6 feature so far? 🚀 #TypeScript #TypeScript6 #JavaScript #WebDevelopment #CodingTips

Unpopular opinion: You should NOT use TypeScript for every project. For small internal tools and quick prototypes, plain JavaScript is faster to write, easier to debug, and your team ships in half the time. TypeScript shines when: - 3+ developers work on the same codebase - The project will be maintained for years - You have complex data models But for a weekend hackathon or MVP? Just ship it in JS. Add types later. What do you think? #TypeScript #JavaScript #WebDev

🚀 Day 966 of #1000DaysOfCode ✨ Interface vs Types in TypeScript (Explained Simply) If you’ve worked with TypeScript, you’ve probably seen both `interface` and `type` — and wondered which one to use. In today’s post, I’ve broken down the difference between interfaces and types in a simple and practical way, so you can understand their real use cases. While both are used to define the shape of data, they behave differently when it comes to extension, flexibility, and advanced use cases like unions and intersections. Understanding when to use `interface` and when to use `type` can make your code more scalable and easier to maintain — especially in large applications. This is one of those concepts that often comes up in interviews and real-world projects. If you’re using TypeScript in your workflow, having clarity on this will level up your code quality. 👇 Do you prefer using `interface` or `type` in your projects?
