JavaScript Functions Explained

𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 𝐯𝐬 𝐓𝐲𝐩𝐞𝐒𝐜𝐫𝐢𝐩𝐭 🤔 JavaScript is fast, flexible, and easy to start with. You can build things quickly, and it runs pretty much everywhere ⚡ But as projects grow, I’ve noticed how runtime errors can slow things down and make debugging stressful 😅 That’s where TypeScript really stands out. Adding static typing, catching errors at compile time, and getting better tooling just makes development feel more controlled and scalable 🛡️ For me: 👉 JavaScript gives speed 👉 TypeScript gives safety and scalability Both have their place — it’s all about choosing the right tool for the right stage of the project.

Day 4/30 – JavaScript Challenge #30daysOfLeetCode Solved LeetCode 2635: Apply Transform Over Each Element in Array using JavaScript ✅ The solution recreates the behavior of Array.map by iterating through the array and applying a given transformation function to each element along with its index. This helps understand how higher-order functions work internally and reinforces fundamentals like loops, function callbacks, and index-based operations. ✅ All test cases passed 📌 Focusing on mastering core JavaScript concepts without relying on built-in methods On to the next challenge 💪 #30DaysOfJavaScript #JavaScript #LeetCode #ProblemSolving #LearningInPublic #CodingJourney #WebDevelopment

JavaScript tip that actually matters 👇 <async/await> doesn’t make code synchronous. It only makes asynchronous code easier to reason about. The event loop, microtasks, and call stack still behave the same — which is why blocking the main thread or misusing promises can still hurt performance. Clean syntax ≠ clean execution. Understanding how JS runs is what separates reliable code from flaky code. #JavaScript #WebPerformance #FrontendEngineering #WebDev #Learning

#letscode #JavaScript #coding Let’s Code JavaScript 🚀 | 30 Days of JS – Day 2️⃣: Hoisting When JavaScript runs a program, it does not execute the code line by line immediately. It first scans the code and sets up memory for variables and functions. 👉 This behavior is called Hoisting. Hoisting is JavaScript’s mechanism where variable and function declarations are processed before code execution begins.

The JavaScript `this` keyword is one of the most important concepts to understand. It refers to the execution context of a function and behaves differently depending on how and where it is called. Mastering `this` helps developers write cleaner and more predictable code in real-world applications. I teach JavaScript concepts daily and apply them through hands-on projects on my YouTube channel, Code Hunter Sharath. 🎥 Playlist: 52 Weeks • 52 JavaScript Projects 👍 Follow for daily JavaScript concepts 🔔 Subscribe to learn by building #JavaScript #LearnJavaScript #WebDevelopment #FrontendDeveloper #Coding

Stop memorizing JavaScript syntax. Started understanding how JavaScript thinks. The moment things clicked: • Execution context • Call stack & event loop • Sync vs async behavior After that, bugs made sense. Performance improved. Debugging became easier. Tools and frameworks help. Fundamentals make you dangerous.

🔍 See JavaScript Code Run Step by Step! I found a cool tool called JS Visualizer 9000. It shows how your JavaScript code actually runs. What it does: • Shows your code running line by line • Visualizes call stack and event loop • Great for understanding async code and promises • Works right in your browser - no install needed Perfect for: • Learning JavaScript basics • Preparing for interviews • Teaching others • Debugging tricky code Try it: jsv9000.app (I made a short video showing how it works!)

Studying how JavaScript works behind the scenes really changed how I understand my code. Learning about scope, lexical scoping, and the different types of scope (global, function, block) helped me see where variables actually live and why some values are accessible while others aren’t. Understanding hoisting and the Temporal Dead Zone (TDZ) also explained many errors I used to see without fully understanding them. Still learning, but these fundamentals are making JavaScript feel less like magic and more predictable😄 #JavaScript #WebDevelopment

Day 13/90 — JavaScript Functions 🔧 Learned how to write reusable code using JavaScript functions. Practiced creating functions with parameters and return values to solve small logic problems. Key takeaway: Functions help write clean, reusable, and structured code. #JavaScript #WebDevelopment #90DaysChallenge #LearningInPublic
