Implementing Selection Sort in JavaScript for Descending Order

🚀 Day 13 of My JavaScript Learning Journey Today I learned about Looping Through Arrays in JavaScript and different ways to iterate over data efficiently. 📌 Key concepts I explored: 🔹 Manual Iteration • for...in → Iterates over indexes • for...of → Iterates over values directly 💡 Best Practice: Avoid using for...in for arrays. Prefer for...of for better readability and reliability. 🔹 Functional Iteration • forEach() → Executes a function for each element • Clean and modern way to write iteration logic Example: arr.forEach((value, index) => { console.log(value, index); }); 🔹 Quick Comparison • for...in → Returns index • for...of → Returns value • forEach() → Uses function (modern approach) 💡 Understanding iteration helps in writing clean, efficient, and readable code, especially when working with large datasets. Step by step, I’m improving my JavaScript fundamentals and coding logic. 💻✨ #JavaScript #WebDevelopment #FrontendDevelopment #CodingJourney #LearningInPublic #DeveloperJourney #ProgrammingBasics

Step by step, improving my coding skills and logic 🚀 #FullStackJourney #WebDevelopment #JavaScript #LearningInPublic #100DaysOfCode #CodingJourney

🚀 Day 31 of My Full Stack Development Journey Today I explored one of the most important concepts in JavaScript — Arrays 📦 Here’s what I learned today: 🔹 Arrays (Data Structure) – Storing multiple values in a single variable 🔹 Visualizing Arrays – Understanding how data is organized 🔹 Creating Arrays – Different ways to define arrays 🔹 Arrays are Mutable – Learning how arrays can be modified 🔹 Array Methods – Working with built-in functions 🔹 indexOf() & includes() – Searching within arrays 🔹 Concatenation & reverse() – Combining and reversing arrays 🔹 Practiced several questions to strengthen my understanding 💻 It’s exciting to see how arrays make handling data much easier and more powerful. Step by step, getting closer to building real-world applications 🚀 #FullStackJourney #WebDevelopment #JavaScript #LearningInPublic #100DaysOfCode #CodingJourney

Today I finally understood how JavaScript actually stores data in memory — and it changed the way I look at code. Earlier, I used to just write variables and functions without thinking much about what’s happening behind the scenes. But now it makes a lot more sense: Primitive values (like numbers, strings, booleans) are stored directly in memory Reference types (like arrays and objects) are stored differently — the variable holds a reference, not the actual value That’s why things like this behave unexpectedly sometimes: Copying objects doesn’t create a real copy Changing one reference can affect another Understanding this cleared up a lot of confusion I had while debugging. Still learning, but this felt like a small breakthrough Hitesh Choudhary Piyush Garg Chai Code #JavaScript #WebDevelopment #100DaysOfCode #LearningInPublic

📘 Big O Notation I’ve been spending some time understanding Big O Notation — it felt confusing at first, but it’s becoming clearer little by little. Big O is a way to understand how efficient our code is as the input size grows. It’s not about exact speed, but about how well an algorithm scales. 💡What I practiced: • Learned the basics like O(1), O(log n), O(n), and O(n²) • Compared how arrays and sets behave in different operations • Used simple loops, map, and forEach to see how performance changes • Wrote small examples to better understand the differences 🧠 My takeaway: Just because code works doesn’t mean it’s efficient. Thinking about performance from the beginning really matters. Still learning, but getting more comfortable with these concepts. #BigONotation #TimeComplexity #CodingJourney #JavaScript #LearningEveryday

🚀 Day 968 of #1000DaysOfCode ✨ Types of Loops in JavaScript (Explained Simply) Loops are one of the most fundamental concepts in JavaScript — but choosing the right one can make a big difference in your code. In today’s post, I’ve explained the different types of loops in JavaScript in a simple and practical way, so you can understand when to use each one. From `for` and `while` to `for...of` and `for...in`, each loop has its own purpose depending on how you’re working with data. Using the right loop not only makes your code cleaner but also improves readability and performance in many cases. This is one of those basics that every developer uses daily — but mastering it helps you write much better code. If you’re working with arrays, objects, or complex data structures, this is something you should be confident about. 👇 Which loop do you use the most in your day-to-day coding? #Day968 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #CodingCommunity #JSBasics

Just wrapped up a sprint focused on core JavaScript fundamentals, and it turned out to be more about thinking clearly than just writing code. A few takeaways: Understanding how modules actually work (CommonJS vs ES Modules) is not optional — it’s foundational Clean data processing (like frequency counting) reveals how well you grasp loops, objects, and structure Fixing bugs blindly wastes time — understanding why they happen is what actually moves you forward I also revisited key concepts like inheritance, mixins, and different programming paradigms (OOP, functional, procedural). Turns out, most mistakes come from weak fundamentals, not complex logic. Next step: go deeper, write less “patchy” code, and focus more on structure and clarity.

Today I explored more concepts in JavaScript and practiced hands-on coding. Topics I covered: ✔️ Variables (let, const) ✔️ Dynamic typing in JavaScript ✔️ Objects (creating, accessing, updating) ✔️ Adding new properties to objects ✔️ Functions inside objects (methods) 💡 Key Takeaway: JavaScript objects are very powerful for storing and managing real-world data, and understanding them is essential for working with APIs and building applications. 📸 Sharing some practice screenshots below.

Day 04 of Learning JavaScript Deep Today’s topic looked simple… but turned out to be powerful Traversing an Array - Visiting each element one by one. Example: let arr = [10, 20, 30, 40]; for (let i = 0; i < arr.length; i++) { console.log(arr[i]); } 🧠 Key understanding: Arrays start at index 0 End at length - 1 One mistake can break logic 👇 for (let i = 0; i <= arr.length; i++) { console.log(arr[i]); // undefined at end ❌ } 💭 Simple thought: “Array is just data… Traversal is how you understand it.” Small concept… big impact 🔥 #Day04 #JavaScript #FrontendDevelopment #LearningDeep #Traversing #Arraybasics

🚀 From Arrays to Efficiency: Mastering Set in JavaScript Today I solved the “Unique Rows in Boolean Matrix” problem using one simple yet powerful concept — Set. At first glance, the problem looks like a typical nested loop challenge. But instead of going brute force, I leveraged Set to achieve a clean and optimal solution. 💡 Key Idea: Convert each row into a string and store it in a Set to automatically handle duplicates. ✨ Why this is powerful: Eliminates duplicates in O(1) lookup time Avoids unnecessary nested loops Keeps the solution clean and readable 📊 Complexity: Time: O(n × m) Space: O(n × m) 🔥 Takeaway: Sometimes, the difference between an average solution and an optimal one is just knowing the right data structure. Today it was Set. Tomorrow, it could be something else. 💬 Curious: Where else have you used Set to simplify a problem? #JavaScript #DSA #CodingInterview #WebDevelopment #ProblemSolving #100DaysOfCode
