Understanding JavaScript Prototype-Based Inheritance

🚀 Understanding the JavaScript Event Loop While learning JavaScript, one concept that really changed how I think about asynchronous code is the Event Loop. JavaScript is single-threaded, which means it can execute only one task at a time. But thanks to the Event Loop, it can still handle asynchronous operations like API calls, timers, and user interactions without blocking the main thread. Here’s the simple flow: 1️⃣ Code enters the Call Stack 2️⃣ Async tasks go to Web APIs 3️⃣ Their callbacks move to the Callback Queue 4️⃣ The Event Loop checks if the Call Stack is empty 5️⃣ Then it pushes the callback into the Call Stack for execution This mechanism is what allows JavaScript to remain non-blocking and highly efficient. Understanding the Event Loop helped me write better asynchronous code using Promises, async/await, and callbacks. If you're learning JavaScript, mastering the Event Loop is a must! 💡 #JavaScript #EventLoop #WebDevelopment #AsyncJavaScript #CodingJourney #FrontendDevelopment

🚀 Day 939 of #1000DaysOfCode ✨ Object Methods in JavaScript Objects are one of the most fundamental parts of JavaScript, and knowing how to work with them efficiently can make your code much more powerful and readable. In today’s post, I’ve covered important object methods in JavaScript that every developer should know. Understanding these methods helps you manipulate data structures more effectively and write cleaner, more efficient code. If you work with JavaScript regularly, mastering object methods is definitely a must. 👇 Which JavaScript object method do you use the most in your projects? #Day939 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #Next #CodingCommunity

🚨 Confused about Hoisting in JavaScript? You’re not alone. 💡 It’s one of those concepts that feels strange at first — but once you get it, your understanding of JavaScript becomes much stronger. 🔹 Hoisting • JavaScript moves declarations to the top of their scope • Happens during the compilation phase • Allows variables and functions to be used before declaration 🔹 var vs let vs const • var → hoisted and initialized with undefined • let & const → hoisted but NOT initialized (Temporal Dead Zone) • Accessing them before declaration throws an error 🔹 Functions • Function declarations → fully hoisted • Function expressions → behave like variables (not fully hoisted) ⚡ Quick rule many developers follow: • var → hoisted safely (but can cause bugs) • let/const → safer, but respect TDZ • Functions → declarations hoisted, expressions not 📌 Hoisting doesn’t move your code — JavaScript just changes how it reads it internally. #JavaScript #WebDevelopment #FrontendDevelopment #Coding #LearnToCode #100DaysOfCode

JavaScript Practice – Day by Day Improvement Today I practiced a JavaScript logic problem “Array Chunking.” The goal was to split an array into smaller subarrays (chunks) of a given size.  Concepts & Methods Used: • for loop for iteration • Array.slice() method to extract subarrays • Incrementing index by chunk size (i += n) for efficient traversal This approach helps break a large array into manageable chunks and improves understanding of array manipulation and problem-solving in JavaScript. I’m focusing on improving my JavaScript logic day by day through consistent practice. 💻 #JavaScript #ProblemSolving #CodingPractice #WebDevelopment #FrontendDevelopment

🚀 Day 930 of #1000DaysOfCode ✨ setTimeout in JavaScript — More Than Just a Delay `setTimeout` looks simple on the surface — just delay something and move on. But behind it lies the core of how JavaScript handles asynchronous behavior. In today’s post, I’ve broken down how `setTimeout` actually works, how it interacts with the event loop, and why the execution order sometimes surprises developers. If you want to truly understand async JavaScript instead of memorizing behavior, this explanation will give you the clarity you need. 👇 Have you ever been confused by the output order when using `setTimeout`? #Day930 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #Next #CodingCommunity #AsyncJavaScript

You know how JavaScript performs one function at a time and it becomes time consuming when a function takes too long to complete? This is because Js is a single threaded language and this behavior is called as synchronous. It can perform one task at a time which blocks other code. This can be solved by using Asynchronous functions (non-blocking way). JavaScript can execute code in two different ways: Synchronous (Blocking) Code runs line by line Each task waits for the previous one to finish If one task is slow, everything else pauses Think of it as a single-lane road. Asynchronous (Non-blocking) Time-consuming tasks run in the background JavaScript continues executing other code Once the task is done, the result is handled. In the next post I will tell how asnyc functions work. See you later. Cheers!! #JavaScript #WebDevelopment #MERN #AsyncJS #LearningInPublic

✨ 𝗗𝗮𝘆 𝟭𝟳 𝗼𝗳 𝗠𝘆 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 𝗝𝗼𝘂𝗿𝗻𝗲𝘆 🚀 Today I explored one of the most important concepts in JavaScript: the 𝗘𝘃𝗲𝗻𝘁 𝗟𝗼𝗼𝗽. I learned why 𝗝𝗮𝘃𝗮𝗦𝗰𝗿𝗶𝗽𝘁 𝗶𝘀 𝘀𝗶𝗻𝗴𝗹𝗲-𝘁𝗵𝗿𝗲𝗮𝗱𝗲𝗱 𝗮𝗻𝗱 𝘀𝘆𝗻𝗰𝗵𝗿𝗼𝗻𝗼𝘂𝘀, yet still capable of handling asynchronous tasks efficiently. Key ideas I understood: 🔹 𝗦𝗶𝗻𝗴𝗹𝗲-𝘁𝗵𝗿𝗲𝗮𝗱𝗲𝗱 𝗻𝗮𝘁𝘂𝗿𝗲 – JavaScript runs one task at a time on a single call stack. 🔹 𝗦𝘆𝗻𝗰𝗵𝗿𝗼𝗻𝗼𝘂𝘀 𝗲𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 – code runs line by line by default. 🔹 𝗘𝘃𝗲𝗻𝘁 𝗟𝗼𝗼𝗽 – manages asynchronous operations by coordinating the 𝗖𝗮𝗹𝗹 𝗦𝘁𝗮𝗰𝗸, 𝗪𝗲𝗯 𝗔𝗣𝗜𝘀, 𝗮𝗻𝗱 𝗖𝗮𝗹𝗹𝗯𝗮𝗰𝗸 𝗤𝘂𝗲𝘂𝗲. This concept finally helped me understand how JavaScript handles things like 𝘁𝗶𝗺𝗲𝗿𝘀, 𝗲𝘃𝗲𝗻𝘁𝘀, 𝗮𝗻𝗱 𝗮𝘀𝘆𝗻𝗰𝗵𝗿𝗼𝗻𝗼𝘂𝘀 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀 without blocking the main thread. #JavaScript #100DaysOfCode #WebDevelopment #LearningJourney #FrontendDevelopment #EventLoop

Day 1 of 30 days of javascript challenge. problem-2667 Problem - Write a function createHelloWorld that returns another function, that returns "Hello World" As this is my first code, I revised my notes on javascript scope. ☑️ Function scope - Any variables declared inside a function body cannot be accessed outside the function body, but global variables can be used inside function body ☑️ Block scope - Any variable declared inside { } cannot be used outside the { } block, although it supports only let and const keyword, var can be used ☑️ Lexical scope - A variable declared outside a function can be accessed inside another function defined after the variable declaration. (The opposite is not true ) This problem uses the concept of closures and higher order functions. Please feel free to discuss where can I improve the code or if you have a different perspective, comment below your views. #javascript #coding #development #motivation #goals #leetcode #webdevelopment

Why == and === Are Not Just Syntax—They're Mindset Shifts! In the world of JavaScript, the difference between == and === is more than just about comparing values. 🙌 When you use ==, you're inviting implicit type conversion into the conversation. This can lead to unexpected results, like comparing a number with a string and getting true. On the other hand, === is the strict operator that doesn’t mess around. It checks both value and type, ensuring your comparisons are as reliable as your coffee maker on a Monday morning. ☕️ Using === is like setting clear boundaries in your code. It prevents those sneaky bugs from creeping in and keeps your logic crystal clear. Why risk confusion when you can make your intentions explicit? 🔍 So, next time you're coding, remember: clarity is key! Which operator do you prefer and why?
