Optimizing Performance with Fewer Libraries

Ever wondered why your JavaScript logs run out of order? This is one of the most common async mistakes. The fix isn’t complex — it’s async/await. Once you see it, you can’t unsee it. Cleaner flow. Predictable output. Better code. Try this pattern in your code today. #JavaScript #AsyncAwait #WebDevelopment #Frontend #SoftwareEngineering #makstyle119

Reposting this 🔁 — Debouncing vs Throttling explained really well 🚀 These two concepts look simple, but they play a huge role in frontend performance. 🔹 Debouncing → waits until the user stops the action (perfect for search inputs) 🔹 Throttling → executes at fixed intervals (great for scroll & resize events) Understanding when and why to use each one can: Reduce unnecessary API calls Improve app performance Create smoother user experiences If you’re working with JavaScript / React, this is a must-know concept. Highly recommend going through this post 👍 Credits: Naganathan A 🙌 #JavaScript #WebDevelopment #Frontend #ReactJS #PerformanceOptimization #Learning #Developers

JavaScript Debouncing vs Throttling — Explained Simply 🚀 Ever wondered why your search input fires API calls too often? Or why scroll events hurt performance? 👉 The answer is Debounce & Throttle. 🔹 Debounce → waits until the user stops the action 🔹 Throttle → runs at fixed intervals, no matter how often the event fires Used commonly in: Search inputs 🔍 Scroll & resize events 📜 Button clicks ⚡ Swipe through to understand: ✔ How they work ✔ When to use which ✔ Common mistakes developers make 💬 What’s your real-world use case for debounce or throttle?

Most grouping bugs I debug in production come from assuming keys are always strings. Object.groupBy() is fine for primitive keys, but anything else gets coerced into a property name. That means object/function keys collapse into "[object Object]", and you lose identity. Map.groupBy() keeps keys by reference, so lookups and merges remain predictable across code paths (assuming your runtime supports it, or you polyfill it). Where in your codebase are you grouping by something that isn’t naturally a string? #javascript #typescript #frontend #webdev

Most developers don’t know this about JavaScript closures 🤯 Closures are not magic. They simply remember the variables even after the function is executed. That’s why: • setTimeout • Event listeners • Callbacks work so smoothly. If closures confuse you → practice small examples, not big codebases.

⚛️ Props vs State — React fundamentals people often mix up Both are everywhere in React. But they solve very different problems. 📦 Props ➡️ Passed from parent to child ➡️ Read-only (child can’t change them) ➡️ Best for configuration & data flow 🧠 State ➡️ Lives inside the component ➡️ Can change over time ➡️ Drives interaction & UI updates 🚫 Common mistake Using state when props are enough. ✅ Simple rule I follow 👉 If the component controls it → State 👉 If the component receives it → Props Mastering this makes your components: ✨ Cleaner ✨ More predictable ✨ Easier to debug #React #Frontend #JavaScript #WebDevelopment #ReactJS

📘 React Hooks — clarity over confusion Today I spent time understanding React Hooks more deeply instead of just “using them blindly”. Here’s what I locked in 👇 🔹 useCallback() • When to use: When we don’t want a function to be recreated on every re-render. • Dependency array: Put the values that are used inside the function and can change between renders. 🔹 useEffect() • When to use: When we want to perform a side effect on render or re-render. • Dependency array: The values which, when changed, should trigger the effect again. 🔹 useRef() • When to use: When we need to store a reference to a DOM/HTML element (without causing re-renders). No shortcuts. No memorization. Just understanding why things work the way they do. Still learning. Still refining. 🚀 #React #JavaScript #WebDevelopment #LearningInPublic #Frontend #ReactHooks #Consistency

Event Capturing & Bubbling in JavaScript — something I wish I understood earlier 🧠 If you’ve ever clicked a button and wondered, "Why is the parent handler also firing?" — This is why. When an event happens, it travels through the DOM in phases: • Capturing → top to bottom • Target → the actual element • Bubbling → bottom to top (default) Most bugs around clicks, modals, dropdowns, and menus come from not knowing this flow. Frontend isn’t hard — It’s just easy to misunderstand when fundamentals are skipped ⚡ #JavaScript #Frontend #WebDev

Ever wondered why useEffect runs twice and thought: “React is broken”? It’s actually doing you a favor. In development, React deliberately re-runs effects to expose: - Hidden side-effects - Missing cleanups - Unsafe logic This behavior occurs in Strict Mode and does not affect production. Once you understand this, you can stop fighting React and start writing effects that are predictable, clean, and future-proof. React isn’t trolling you; it’s training you. #React #ReactHooks #Frontend #JavaScript #WebDevelopment

Ever stared at your console and screamed, "Why is this function repeating itself?!" The Answer: It usually happens when you perform a state update inside a useEffect hook but forget the dependency array. Here is what is happening under the hood: The component renders. The effect runs and updates the state. The state update triggers a re-render. Without a dependency array, the effect runs again... and the cycle never ends. To fix it, always define when the effect should run by adding [] (run once) or [prop] (run on change). #ReactJS #JavaScript #WebDevelopment #CodingTips #SoftwareEngineering #Frontend
