Practiced JavaScript DOM manipulation and learned how to interact with elements in real time.

A closure in JavaScript is when a function remembers and accesses variables from its outer scope, even after that outer function has returned. #javascript #typescript #frontend #backend

🚀 Just finished a small JavaScript project! I built a modal window that opens and closes when clicking buttons, the overlay, or pressing the Escape key. 🧠 This helped me understand: - querySelector / querySelectorAll - addEventListener - classList.add() and .remove() - Keyboard events like keydown Check out the full project on GitHub 👇 🔗 https://lnkd.in/euzZQVBA #JavaScript #WebDevelopment #Frontend #LearningInPublic #Makhilens

⚡ JavaScript Trick of the Day Do you know the difference between map() and forEach()? • map() → returns a new array • forEach() → just loops through Which one do you use more often? 👇 #javascript #frontend #codingtips

Going back to basics 🌱 What does "typeof null" returns ?? Surprisingly, it returns "object" Yes it has been a "bug" in Javascript since the very beginning as i have read. When Javascript was first designed, values were stored in a way that caused "null" to be mistakenly tagged as an "object". And even after years, it remains that way for backward compatibility. So, "typeof null" is "object" but null is not an "object". #Javascript #Frontend

Built a simple counter app to practice vanilla JavaScript DOM manipulation. Hooked up event listeners for increment, decrement, and reset and stored progress to Local Storage. It's all about making the page interactive!

Daily tip: Use optional chaining in JavaScript to safely access nested properties. Example: const city = user?.address?.city ?? 'Unknown'. Small trick, big payoff. If you’re exploring React, remember to keep components focused and reusable. What's your current favorite JS trick? #JavaScript #React #WebDev

I’ve broken down 3 golden rules to write predictable, bug-free state management in Redux — all in a visual, easy-to-digest format. Whether you’re a React beginner or a frontend pro, these rules will help you: ✅ Write pure reducers ✅ Keep state immutable ✅ Keep reducers synchronous 💡 Carousel slides include short explanations and code examples so you can apply them instantly in your projects. Check it out and let me know: Which rule do you think is most often broken? #Redux #ReactJS #ReduxToolkit #FrontendDevelopment #JavaScript #WebDev #HamzaNazir

Okay, Day 9 was all about leveling up the JavaScript foundation. I spent the day deep-diving into Arrays, and honestly, they're the best! An array is essentially a super-powered list that lets you store a ton of information—like every item on a menu—under one neat variable. Getting comfortable with array methods like .push() and .forEach() feels like I've just unlocked a huge part of dynamic web building. It's the difference between hard-coding everything and letting JavaScript manage the content for me. Feels good to get this fundamental piece of logic fully wired! Question: Why is using an array (like dishes = ["soup", "salad"]) so much better than just using a bunch of separate variables (like dish1, dish2, dish3) when dealing with dozens of items?" #Javascript #arrays #31dayschallenge #webdevelopment #frontend

Today I learned about three important JavaScript loops: forEach() for...in for...of Each one has its own purpose: forEach() — used to loop through array elements for...in — used to iterate over object keys for...of — used to loop through iterable values like arrays or strings Understanding the difference between them really cleared things up for me 💡 #JavaScript #WebDevelopment #LearningJourney #Frontend #100daysofcode
