Hello Everyone👋👋 What is the purpose of the throw and throws keywords? throw: Used to explicitly throw an exception from a method or block of code. throws: Used in a method signature to declare that a method might throw one or more specified types of checked exceptions. It informs the caller that they need to handle or declare these exceptions. #Java #backend #frontend #FullStack #software #developer #programming #code #Java26 #class #object #inheritance #abstract #interface #GenAI #AI #OpenAI #Claude #LLM #RAG #Langchain #Nodejs #React #SystemDesign #Array #ArrayList #collections #interview

🚀𝐈 𝐛𝐮𝐢𝐥𝐭 𝐦𝐲 𝐨𝐰𝐧 𝐂 𝐂𝐨𝐦𝐩𝐢𝐥𝐞𝐫 — 𝐚𝐧𝐝 𝐢𝐭'𝐬 𝐧𝐨𝐰 𝐋𝐈𝐕𝐄! I'm excited to share my latest project: Mini C Compiler — a complete web-based C compiler with Lexical, Syntax, Semantic Analysis, and Code Generation! 🔥 💡 𝗪𝗵𝗮𝘁 𝗺𝗮𝗸𝗲𝘀 𝘁𝗵𝗶𝘀 𝘀𝗽𝗲𝗰𝗶𝗮𝗹? This compiler processes C code through all 5 major compilation stages: ✅ 𝗟𝗲𝘅𝗶𝗰𝗮𝗹 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀 — Converts code into tokens with line & column tracking ✅ 𝗦𝘆𝗻𝘁𝗮𝘅 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀— Builds an Abstract Syntax Tree (AST) ✅ 𝗦𝗲𝗺𝗮𝗻𝘁𝗶𝗰 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀 — Generates Symbol Table with type checking ✅ 𝗖𝗼𝗱𝗲 𝗚𝗲𝗻𝗲𝗿𝗮𝘁𝗶𝗼𝗻 — Produces optimized output code ✅ 𝗠𝗼𝗱𝗲𝗿𝗻 𝗨𝗜 — Clean interface with 5 structured output tabs 🌐 𝗟𝗶𝘃𝗲 𝗗𝗲𝗺𝗼: 👉 https://lnkd.in/gEHeU8xU ⚙️ 𝗧𝗲𝗰𝗵 𝗦𝘁𝗮𝗰𝗸: 🔹 C++ (Core compiler logic) 🔹 Node.js + Express (Backend API) 🔹 React.js (Frontend UI) 🔹 Render (Hosting) 📂 𝗚𝗶𝘁𝗛𝘂𝗯 𝗥𝗲𝗽𝗼𝘀𝗶𝘁𝗼𝗿𝘆: 👉 https://lnkd.in/gNJqEtcf This project helped me deeply understand how compilers work under the hood — from tokenization to execution. I’d love to hear your feedback and suggestions! 🙌 #CCompiler #WebDevelopment #ReactJS #NodeJS #CPlusPlus #CompilerDesign #SideProject #Programming

Problem: JavaScript’s `.sort()` mutates the array. Solution: Use `.toSorted()` instead. It returns a new sorted array. —— 👋 Join 30,000+ SWEs learning JS, React, Node.js, and Software Architecture: https://thetshaped.dev/ ——— 💾 Save this for later. ♻ Repost to help others find it. ➕ Follow Petar Ivanov + turn on notifications. #javascript #softwareengineering #programming

🚀 A small habit that makes you a better developer: Write code for humans. Not for computers. Because computers don’t care about your code… But developers do. ✔️ Readable code ✔️ Clear naming ✔️ Simple logic Clean code isn’t just about today… It’s about the next developer who will read, fix, or extend your work. And sometimes… that developer is YOU after 3 months 😄 💡 Future developers will thank you. ⸻ 💬 What’s one habit that improved your code quality? ⸻ #frontend #webdevelopment #softwareengineering #programming #cleanCode #javascript #reactjs #developers #coding #softwaredevelopment #tech #programmerlife #devtips #codinglife #buildinpublic

One small JavaScript concept. Big real-world impact. If you don’t understand mutable vs immutable data, you’ll eventually hit bugs you didn’t expect. Especially in React. Mutable = flexible Immutable = safer Good developers know when to use each. Which causes more pain in real projects: mutation bugs or async bugs? 👇 #javascript #reactjs #frontenddevelopment #webdevelopment #softwareengineering #programming

Unpopular opinion: Most developers are overengineering simple projects. Adding layers… Using complex patterns… Chasing “perfect architecture”… For apps that don’t even need it. I’ve seen small Laravel projects with: 👉 Repository pattern 👉 Service layers 👉 Event systems 👉 Microservice ideas All for something that could’ve been built simply. And in the end? ❌ Slower development ❌ More bugs ❌ Harder to maintain The truth is: Not every project needs complexity. Sometimes… simple code with clear structure wins. Architecture should solve problems — not create them. So here’s the real question: Are we building better systems… or just more complicated ones? 👇 #Laravel #PHP #SoftwareEngineering #Developers #Programming #CleanCode #BackendDevelopment #TechDebate #Coding

💡 How React Connects State to Input? In React, inputs are controlled using State. This means React controls what user types. 👉 Input value = State value 👉 On typing → State updates 👉 State updates → UI updates This is called a Controlled Component. 📌 Why important? • Form validation • Dynamic UI updates • Better data handling • Predictable behavior ⚡ This is one of the most important React fundamentals.

useMemo and useCallback are slowly becoming a code smell. Yes… I said it. With the React Compiler growing in 2026, manual optimization is becoming less necessary. Instead of this: const value = useMemo(() => compute(a, b), [a, b]); We’re moving towards: → Cleaner code → Fewer bugs → Compiler-driven optimization The real skill now is not optimizing manually. It’s writing code the compiler can optimize. Are we over-engineering React apps today? 👇 #React #JavaScript #Frontend #WebDevelopment #TechTrends  #SoftwareArchitecture #CleanCode #Programming #DevDiscussion #FutureOfTech

Ever faced a situation where a small error breaks your entire application? 😓 That’s where try...catch...finally comes to the rescue. 💡 Here’s what every developer should know: 🔹 try → Wrap risky code 🔹 catch → Handle errors gracefully 🔹 finally → Always runs (cleanup, logging, etc.) 👉 Plus, you can even throw custom errors to enforce rules in your code. ⚡ Why it matters: ✔ Prevents app crashes ✔ Improves user experience ✔ Makes debugging easier ✔ Gives you control over failures 🧠 Pro Tip: Great developers don’t just write code… They write code that handles failure smartly. 💬 What’s the most common error you’ve faced in JavaScript? #JavaScript #WebDevelopment #Coding #Frontend #Programming #Developers #ErrorHandling #LearnToCode #100DaysOfCode #chaicode #chaiaurcode Chai Aur Code #try #error #catch #finally
