Day 5 of 100 days. A situation many developers encounter when working with JavaScript, especially at the early stages… You write your code, trigger an action, and expect a response - but nothing happens. No error. No output. Just silence. And it’s not just beginners - this is a common experience across all levels. The challenge: JavaScript not responding 👉 What I always advise: • Ensure your script is properly linked • Confirm the DOM has fully loaded before running your code • Use console.log() to trace and debug your logic Often, the issue isn’t complex - it’s simply hidden. Do you use console.log() when debugging, or do you have another favorite method?

🚀 Mastering JavaScript Array Methods Understanding array methods is a game-changer when writing clean, efficient JavaScript code. Here’s a quick breakdown of some essential ones: 🔹 map() – Transforms each element in an array 🔹 forEach() – Executes a function for every element 🔹 filter() – Selects elements based on a condition 🔹 push() & pop() – Add/remove elements from the end 🔹 shift() & unshift() – Add/remove elements from the beginning 🔹 reduce() – Combines elements into a single value These methods help simplify data manipulation and make your code more readable and powerful. Whether you're transforming data, filtering results, or aggregating values, knowing when to use each method can level up your JavaScript skills. 💡 Pro tip: Use map() for transformations and reduce() for calculations or summaries. #JavaScript #WebDevelopment #Coding #Frontend #Programming #DeveloperTips

Practicing JavaScript Strings with a simple hands-on project 💻 Built a couple of small projects,out of them one is here 🔹 Convert text to UPPERCASE & lowercase 🔹 Remove extra spaces 🔹 Replace specific words dynamically This helped me improve my understanding of: ✔ String methods ✔ Regular expressions for cleaning text ✔ DOM manipulation & event handling #JavaScript #WebDevelopment #Frontend #CodingPractice #LearningJourney

I used to believe that JavaScript operated with some hidden “thread algorithm” behind the scenes. However, I learned that it doesn't function that way. JavaScript is single-threaded, yet it effectively manages multiple tasks simultaneously through the event loop, not threads. Here's a simplified breakdown: - There’s one main worker (the call stack). - There’s a waiting area (task queues). - There’s a loop that continuously checks what to run next. The core flow looks like this: while (true) { run sync code first if nothing is running: run all microtasks (Promises) then pick one macrotask (timers, I/O) } What surprised me the most is the priority system: Promises always execute before timers. Even a setTimeout(..., 0) has to wait its turn. As for the “threading” aspect? It exists, but not in the way you might expect. The engine (like V8) runs your code in a single thread, while the environment (browser or Node.js) utilizes multiple threads for tasks like network calls and timers. In essence, JavaScript doesn’t schedule threads; it schedules tasks. This shift in perspective can significantly change your understanding of asynchronous code. #javascript #learning #webdevelopment #programming #codewithishwar

Day 3 — JavaScript is humbling me in the best way. Started with the basics I thought I already knew. Turns out I knew the syntax but not the why. var vs let vs const — I used to just pick randomly. Now I get why const is default and var is basically legacy. The thing that actually clicked today: arrow functions aren't just shorter syntax. They handle 'this' differently. That's why everyone prefers them in certain situations. Also spent an hour on map, filter, and reduce with real data instead of fake tutorials. Way more useful. Favourite thing I learned: optional chaining (?.) — it's saved me from so many "cannot read property of undefined" errors already.

A classic JavaScript quirk that often trips developers up: why does typeof null equal "object"? This behavior dates back to the very early days of JavaScript. It's a known inconsistency, not a bug in the sense of broken functionality, but certainly a surprising one. Understanding this nuance is crucial for writing robust JavaScript. Always remember that checking `value === null` is the reliable way to test for a null value, rather than relying on `typeof`. Mastering these JavaScript oddities helps us build more predictable and maintainable code. #JavaScript #Programming #WebDevelopment #DeveloperTips

JavaScript becomes a different language the moment you realize this: 👉 Functions are not just reusable blocks… they are values. And once you understand that, concepts like callbacks and higher-order functions stop feeling confusing and start feeling natural. In this video, I’ve broken it down step by step: How values behave in JavaScript How objects behave Why functions behave the same way (and why that matters) From there, everything builds logically: ✔ Passing functions as arguments ✔ Returning functions from functions ✔ What exactly a callback is ✔ What a higher-order function is ✔ How this leads to more flexible and reusable code No jargon. No unnecessary complexity. Just a clear, practical approach to a core JavaScript concept. 🎥 Watch here: https://lnkd.in/gM8ibZ6M This is Part 1 — next, we’ll explore how this shows up in real code with: setTimeout, forEach, map, filter #JavaScript #WebDevelopment #FrontendDevelopment #Programming #Coding #LearnToCode #JavaScriptDeveloper #SoftwareDevelopment #Developers #CodingJourney #TechEducation #Hosiyar #JS

JavaScript gets a lot more interesting when callbacks stop feeling like definitions and start feeling like real tools. In this video, I continue the callbacks discussion by showing where these ideas actually appear in day-to-day JavaScript code. This session covers: • how forEach() works • how map() helps transform data • how filter() helps us select data based on conditions • how all of these use callback functions internally • how JavaScript normally behaves in a synchronous flow • and a first glimpse of asynchronous behavior using setTimeout() I also tried to explain when synchronous flow makes sense and when asynchronous behavior becomes useful, using practical examples and simple coding demonstrations. The goal was not just to teach the syntax of forEach(), map(), and filter(), but to help connect them with the bigger idea of callbacks in real JavaScript.
