Arrow functions are one of the most widely used features in modern JavaScript — especially in React applications. But many developers don’t clearly understand why they are preferred over traditional functions. In this short video, I explain: • Difference between normal functions and arrow functions • How arrow functions simplify syntax • How to create functions without the function keyword • Assigning functions to variables • Writing cleaner and more maintainable code Arrow functions help you write code that is: • Shorter • Cleaner • Easier to manage This is a foundational concept for frontend developers working with React. 🎓 Learn JavaScript & React with real-world projects: 👉 https://lnkd.in/gpc2mqcf 💬 Comment LINK and I’ll share the complete JavaScript roadmap. #JavaScript #ReactJS #FrontendEngineering #WebDevelopment #SoftwareEngineering #Programming #DeveloperEducation
Why Arrow Functions Are Used Everywhere in React

Stop using 𝗮𝗻𝘆 in TypeScript 🚀 The whole point of TypeScript is to bring type safety to JavaScript. So when I still see any in codebases, PRs, or interviews — it’s usually a 🔴 red flag. Yes, TypeScript provides 𝗮𝗻𝘆 for edge cases. But let’s be honest… most of the time, it’s used to silence the compiler instead of fixing the problem. (PS: Hey compiler, shut the hell up and ignore my mistake 😅) And when you do that, you’re essentially opting out of everything TypeScript is trying to help you with. You’re not “𝙬𝙤𝙧𝙠𝙞𝙣𝙜 𝙬𝙞𝙩𝙝 𝙏𝙮𝙥𝙚𝙎𝙘𝙧𝙞𝙥𝙩” anymore — you’re just writing JavaScript with extra steps 😅 Instead, try: → unknown when the type isn’t clear yet → proper interfaces or generics → narrowing with type guards TypeScript is at its best when you let it guide you — not when you bypass it. Use any as a last resort, not a default.

While learning React, I made a mistake that slowed me down… I used useEffect for everything. Fetching data Updating state Even simple calculations At first, it felt powerful. But soon my code became: Confusing Hard to debug Full of unnecessary logic Then I realized something important: 👉 Not everything belongs in useEffect Now I: • Keep logic simple • Avoid unnecessary state • Use hooks only when needed The biggest lesson: Clean code > clever code Curious to know: What confused you most while learning React? #ReactJS #FrontendDeveloper #WebDevelopment #JavaScript
