How to use Object.assign() in JavaScript for object manipulation

👨🏻💻 Post 23 — Object.entries() in JavaScript Ever wanted to loop through both the keys and values of an object easily? 🤔 That’s exactly what Object.entries() does! It turns your object into an array of [key, value] pairs — perfect for looping with for...of or using array methods like map()! 👨🏻🏫 Example in the media of this post! 🤔 Why it’s useful: • Makes it easy to work with objects like arrays. 🔁 Follow for more simple and useful JavaScript tips! #webdevelopment #fullstack #frontend #backend #javascript

⚡ 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

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

🚀 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐅𝐚𝐥𝐬𝐲 𝐕𝐚𝐥𝐮𝐞𝐬 𝐢𝐧 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 In JavaScript, some values are considered “falsy”, meaning they behave like false when used in a condition. Falsy values are: 𝐟𝐚𝐥𝐬𝐞, 0, "", 𝐮𝐧𝐝𝐞𝐟𝐢𝐧𝐞𝐝, 𝐧𝐮𝐥𝐥, 𝐍𝐚𝐍 💡 Tip: Any value that’s not falsy is automatically 𝐭𝐫𝐮𝐭𝐡𝐲 — for example: 'hello', 1, [], {}, true are all 𝐭𝐫𝐮𝐭𝐡𝐲. 👉 JavaScript quietly checks for truthy or falsy behind the scenes! #JavaScript #WebDevelopment #Frontend #CodingTips #LearnJS

I’ve been brushing up on my basics with a fun mini project — a Basic Calculator built using HTML, CSS, and JavaScript. It’s simple, sleek, and comes with a clean UI, dark/light mode, and even memory buttons! A great way to practice core concepts while making something actually useful. Check it out and calculate in style : https://lnkd.in/gnk__3mX Would love to hear your thoughts or suggestions! #WebDevelopment #Frontend #JavaScript #HTML #CSS #LearningByDoing #CodingJourney #BuildInPublic

When I first learned JavaScript, hoisting felt confusing — but it’s actually simple. Hoisting means: JavaScript moves variable and function declarations to the top of their scope before executing the code. So you can use a variable or function before it's declared — but the results depend on how it’s declared. 🧠 Why does this happen? var is hoisted and initialized as undefined → no error. let and const are hoisted but stay in the Temporal Dead Zone (TDZ) → error if accessed before initialization. Function declarations are fully hoisted → you can call them before writing them. 💡 In short: ✔ var → hoisted, value = undefined ✔ function → fully hoisted ❌ let & const → hoisted but not usable (TDZ) #JavaScript #Hoisting #WebDevelopment #Frontend #LearnInPublic #MERNStack #30DaysOfCode

🎙️ Just launched my Text-to-Speech Converter built with HTML, CSS, and JavaScript! A simple yet powerful tool that converts written text into natural-sounding speech — enhancing accessibility and user interaction. 💻 Check out the project on GitHub: [https://lnkd.in/diTUi4xp] #WebDevelopment #JavaScript #Accessibility #FrontEnd #CodingJourney

🔥 Callback Hell one of the first nightmares every JavaScript developer faces In JavaScript, callbacks are functions passed as arguments to handle asynchronous tasks. They work fine... until you start nesting them 👇 getUser(id, (user) => { getPosts(user.id, (posts) => { getComments(posts[0].id, (comments) => { console.log(comments); }); }); }); Looks familiar? 😅 That’s Callback Hell — deeply nested callbacks that make code hard to read, debug, and maintain. 💡 How to fix it: Use Promises or async/await for cleaner and more readable async code. const user = await getUser(id); const posts = await getPosts(user.id); const comments = await getComments(posts[0].id); Same logic — but much more elegant ✨ Callback Hell teaches one of the best lessons in JavaScript: Write async code that reads like sync code. Have you ever refactored a callback mess into async/await? #JavaScript #WebDevelopment #Frontend #React #ReactJS
