How to Rotate an Array in JavaScript with Reverse

The next generation of frontend performance won’t be written in JavaScript, it’ll run beside it. WebAssembly with Rust means faster and safer web. Are you experimenting with Wasm yet? #WebDevelopment #Rust #Wasm #Coding

💡 7 Core JavaScript Concepts Every Developer Should Know 💡 If you've ever felt stuck understanding why JS behaves “weird,” these slides are for you. From Closures to Event loops, this carousel breaks down the logic behind the most common interview and real-world topics in simple words and examples. Mastering these will make your code more predictable, maintainable, and bug-free. #javascript #webdevelopment #frontend #developers #programming #coding #softwaredevelopment #learnjavascript #codetips 

Learning by building: wrote a simple JS program that takes a number and prints its multiplication table with clean loops, input validation, and readable template strings. Small steps, consistent commits, better logic every day. 🚀 #JavaScript #VSCode #100DaysOfCode #BuildInPublic”

Let’s decode three of the most confusing JavaScript topics 👇 🔹 1. Scope Scope defines where your variables and functions are accessible. Global Scope: Accessible everywhere in the code. Function Scope: Accessible only inside a function. Block Scope: (introduced with let & const) accessible only within { }. 🔹 2. Hoisting JavaScript moves declarations to the top of their scope before code execution. But remember — only declarations are hoisted, not initializations. That’s why var behaves differently than let and const. 🔹 3. TDZ (Temporal Dead Zone) The period between entering a scope and initializing a variable declared with let or const. Accessing a variable in TDZ results in a ReferenceError — it exists but isn’t accessible yet! #JavaScript #FrontendDevelopment #WebDevelopment #Coding #Programming #LearnToCode #Scope #Hoisting #TDZ

💭 A small JavaScript curiosity for today I was playing around with this simple piece of code 👇 let a = 5; let b = a; b = 10; const obj1 = { value: 5 }; const obj2 = obj1; obj2.value = 10; console.log(a, b, obj1.value); What do you think will be logged here? And more importantly, why does it behave that way? I’d love to hear your thoughts 👇 #javascript #frontend #learning #developers #coding

🚀 Rotate a Matrix by 90° in JavaScript! Ever wondered how to rotate an image or a matrix by 90 degrees clockwise? Here’s a simple and efficient approach 👇 🔹 Steps 1️⃣ Transpose the matrix (swap rows and columns) 2️⃣ Reverse each row 💡 This combination gives you a 90° clockwise rotation — in just a few lines of code! #JavaScript #Coding #Developers #ProblemSolving #TechTips

JS Tutorial #3: Functions Title: JS Tutorial #3: Functions in JavaScript Content: Functions are reusable blocks of code. They help organize your program. Code snippet: function greet(name) { return `Hello, ${name}!`; } console.log(greet("Cognothink")); Engagement: Write a function that takes two numbers and returns their sum. Try it out! #JavaScript #WebDevelopment #Coding #LearnJS #Cognothink

Just wrapped up a deep dive into JavaScript Objects! 💡 Key takeaways: - They're collections of key-value pairs (properties and methods). - Mastered accessing them with dot and bracket notation. - Crucially, they are mutable (even with const) and passed by reference. A fundamental building block of JS! On to the next concept. #JavaScript #WebDevelopment #Coding #Codecademy

🚀 Day 19 of JS series by Rohit Negi Today, I learned about one of the most important concepts in modern JavaScript — Promises! Here’s what I explored 👇 ✅ What a Promise is and how it’s created ✅ How to handle Promises using .then() and .catch() ✅ What JSON (JavaScript Object Notation) is. It is independent of programming languages ✅ How Promises help solve the callback hell problem #JavaScript #WebDevelopment #LearnInPublic #AsyncJS #Promises #CodingJourney

🚀 Did you know? In JavaScript, setTimeout(..., 0) doesn’t actually run immediately. It runs after all Promises and await calls — even if the delay is 0ms 🧠 Why? Because JS runs all microtasks (like Promises and await) before moving on to macrotasks (like setTimeout, setInterval, etc.). 💡 Takeaway: Understanding the event loop helps you fix async bugs and write smoother, predictable code. #JavaScript #Coding #WebDevelopment #EventLoop #AsyncProgramming #CodeTips #Developers #Learning #letsLearnWithPrateek #Day7 Here’s proof 👇
