JavaScript Event Loop Tutorial with Examples

Day 7/30 – JavaScript Challenge 🚀 Built a Random Quote Generator using JavaScript 💬   On each button click, a random quote is selected from an array and displayed dynamically. GitHub: https://lnkd.in/djJ-NtGi #JavaScript #WebDevelopment #LearningInPublic #30DaysOfCode

🚀 JavaScript Tip: call(), apply() & bind() Confused about this in JavaScript? These 3 methods will clear it up instantly 👇 🔹 call() 👉 Executes immediately 👉 Arguments passed one by one 🔹 apply() 👉 Executes immediately 👉 Arguments passed as an array 🔹 bind() 👉 Returns a new function 👉 Executes later with fixed this 💡 Remember: call & apply → Run now bind → Run later Level up your JavaScript fundamentals 💪 #JavaScript #WebDeveloper #FrontendDeveloper #Coding #LearnJavaScript #TechTips

Understanding var, let, and const in JavaScript ⚡ Many beginners ask: Which one should I use — var, let, or const? 👉 var Function scoped Can be re-declared & updated Causes unexpected bugs ⚠️ Avoid using in modern JavaScript 👉 let Block scoped Can be updated but not re-declared Best for values that change 👉 const Block scoped Cannot be re-assigned Best for fixed references 💡 Rule of Thumb: Use const by default, use let when value needs to change, avoid var. Strong fundamentals = clean & bug-free code 🚀 #JavaScript #WebDevelopment #FrontendDeveloper #LearnJS

Ever seen a JavaScript function “remember” a variable long after the outer function has finished? That behavior comes from closures — one of the most important concepts in JavaScript. In this carousel, I break down closures using the classic counter example so the idea finally clicks: How the outer function creates a variable Why the inner function still has access to it How JavaScript keeps that scope alive Why the counter keeps increasing And where closures show up in real-world code Follow CodebreakDev for more developer fundamentals and clean JavaScript explainers. #javascript #webdevelopment #softwareengineering #codingtips #learninginpublic #programmingfundamentals #frontenddevelopment #CodebreakDev

Most people learn JavaScript functions but very few understand why there are so many ways to write them. Function declaration, expression, arrow, IIFE… each exists for a real reason in real projects. Once you understand when to use what, JavaScript starts making sense. Saving this for future reference 📌 #JavaScript #FrontendDevelopment #WebDevelopment

⚡ JavaScript & TypeScript Daily Refresher #116 👉 What is a prototype in a JavaScript object? 💡 A prototype is an internal object that JavaScript uses for inheritance. When a property or method isn’t found on an object, JavaScript looks it up in its prototype chain. ✨ I post daily JS/TS refreshers — follow for the next one! #JavaScript #TypeScript #Prototypes #WebDevelopment

JavaScript Notes to Escape Tutorial Hell (14/20) JavaScript is a single-threaded language. It has one call stack and can only do one thing at a time. So, why doesn't your entire browser freeze every time you click a button or wait for a timer? The answer is the Callback Function. It handles timers, clicks, and async tasks smoothly. This deck explains: - What callback functions really are - How callbacks enable asynchronous behavior - Why setTimeout and event listeners don’t block execution - How closures maintain state (like a click counter) - How callbacks interact with the call stack - Why unmanaged event listeners can cause memory issues Callbacks are powerful, but only when you understand how they work internally. #JavaScript #WebDevelopment #Callbacks #Asynchronous #CodingJourney #SoftwareEngineering #InterviewPrep #FrontendDeveloper

🤔 If JavaScript allows creating objects without classes, why do we still need classes? I explored this question in my second blog post, along with a clear explanation of instance functions vs static functions in JavaScript. Learning through doubts helps strengthen concepts — Learn via Unlearning. Would love to hear your thoughts! 🔗 Blog link: https://lnkd.in/gVA4KCXb #JavaScript #LearningInPublic #WebDevelopment

🚀 JavaScript Practice: To-Do List I built a simple To-Do List using vanilla JavaScript to strengthen my core JS skills. In this practice project, I worked with: prompt() for user input Objects to store each task Array methods: push() to add tasks findIndex() to locate a task splice() to delete tasks forEach() to loop through all task objects This exercise helped me better understand array manipulation, object handling, and basic JavaScript logic without using any frameworks. 📌 Small projects like this make learning JavaScript more practical and fun! #JavaScript #LearningByDoing #WebDevelopment #ToDoList #ProgrammingPractice
