JavaScript Event Loop Explained

🚀 JavaScript Simplified Series — Day 35 Prototypes are powerful… But let’s be honest 😅 👉 Syntax thoda confusing lagta hai 👉 Hard to read 👉 Not beginner friendly What if we could write the same thing in a **clean and simple way?** 🤔 --- ## 🔥 Solution → Classes --- ## 🔹 What are Classes? Classes are just a **clean syntax over prototypes** 👉 Same power 👉 Better readability --- ## 🔹 Without Class (Old Way) ```javascript id="clx1" function User(name) { this.name = name } User.prototype.greet = function() { console.log("Hello " + this.name) } let u1 = new User("Abhay") u1.greet() ``` --- ## 🔹 With Class (Modern Way 😎) ```javascript id="clx2" class User { constructor(name) { this.name = name } greet() { console.log("Hello " + this.name) } } let u1 = new User("Abhay") u1.greet() ``` 👉 Same result 👉 Cleaner code --- ## 🔹 Adding More Methods ```javascript id="clx3" class User { constructor(name) { this.name = name } greet() { console.log("Hello " + this.name) } sayBye() { console.log("Goodbye") } } ``` --- ## 🔥 Real Life Example Think of a **blueprint 🏗️** 👉 Class = blueprint 👉 Object = actual building Same design → multiple objects --- ## 🔥 Simple Summary Class → cleaner syntax Constructor → initialize values Methods → behavior --- ### 💡 Programming Rule **Write code that humans can read.

🚀 JavaScript Simplified Series — Day 26 You click a button… But nothing happens immediately 😳 Instead… it waits. Then suddenly → response comes. How does JavaScript handle this? 🤔 🔥 The Problem JavaScript runs line by line (synchronously) console.log("Start") console.log("Process") console.log("End") 👉 Output: Start Process End Everything runs one after another 😵 But Real World is Different Think about: 👉 API calls 👉 File loading 👉 Timers They take time ⏳ If JavaScript waits… everything will freeze ❌ 🔥 Solution → Asynchronous JavaScript JavaScript can handle tasks without blocking execution 🔹 Example with setTimeout console.log("Start") setTimeout(() => { console.log("Delayed Task") }, 2000) console.log("End") 👉 Output: Start End Delayed Task 🔍 What’s happening? 👉 setTimeout runs later 👉 JavaScript doesn’t wait 👉 Code continues execution 🔹 Callback in Async setTimeout(function() { console.log("Task Done") }, 1000) 👉 Function runs after delay 📌 This function is a callback 🔥 Real Life Example Ordering food 🍔 You order → wait Meanwhile → you do other work Food arrives later 👉 That’s async behavior 🔥 Simple Summary Sync → line by line execution Async → non-blocking execution Callback → function runs later 💡 Programming Rule Don’t block execution. Let JavaScript handle tasks asynchronously.

🚀 JavaScript Simplified Series — Day 36 You created a class… Now imagine 👇 You want another class with: 👉 Same properties 👉 Same methods 👉 Plus some extra features Will you rewrite everything again? ❌ That’s inefficient 😵 --- ## 🔥 Solution → Inheritance --- ## 🔹 What is Inheritance? Inheritance allows one class to: 👉 **Reuse properties & methods of another class** --- ## 🔹 Example ```javascript id="inh1" class User { constructor(name) { this.name = name } greet() { console.log("Hello " + this.name) } } class Admin extends User { deleteUser() { console.log("User deleted") } } let admin = new Admin("Abhay") admin.greet() admin.deleteUser() ``` 👉 Output: Hello Abhay User deleted --- ## 🔍 What’s happening? 👉 `Admin` inherited from `User` 👉 So it gets `greet()` automatically 👉 Plus its own method --- ## 🔹 super keyword ```javascript id="inh2" class Admin extends User { constructor(name, role) { super(name) this.role = role } } ``` 👉 `super()` calls parent constructor --- ## 🔥 Real Life Example Think of a **family 👨👩👧** 👉 Parent → basic traits 👉 Child → inherits + adds new traits --- ## 🔥 Simple Summary extends → inheritance super → parent constructor Reuse → no duplication --- ### 💡 Programming Rule **Don’t rewrite code. Reuse it with inheritance.** --- If you want to learn JavaScript in a **simple and practical way**, you can follow these YouTube channels: • Rohit Negi • Hitesh Choudhary (Chai aur Code) --- 📌 Series Progress Day 1 → What is JavaScript Day 2 → Variables & Data Types Day 3 → Type Conversion & Operators Day 4 → Truthy & Falsy + Comparison Operators Day 5 → If Else + Switch + Ternary Day 6 → Loops Day 7 → Break + Continue + Nested Loops Day 8 → Functions Basics Day 9 → Arrow + Default + Rest Parameters Day 10 → Callback & Higher Order Functions Day 11 → Arrays Basics Day 12 → Array Methods Day 13 → Array Iteration Day 14 → Advanced Array Methods Day 15 → Objects Basics Day 16 → Object Methods + this Day 17 → Object Destructuring Day 18 → Spread & Rest Day 19 → Advanced Objects Day 20 → DOM Introduction Day 21 → DOM Selectors Day 22 → DOM Manipulation Day 23 → Events Day 24 → Event Bubbling Day 25 → Event Delegation Day 26 → Async JavaScript Day 27 → Promises Day 28 → Async / Await Day 29 → Fetch API Day 30 → Event Loop Day 31 → Scope Day 32 → Hoisting Day 33 → Closures Day 34 → Prototypes Day 35 → Classes Day 36 → Inheritance Day 37 → Modules (Next Post) --- Follow for more 🚀 #JavaScriptSimplified #javascript #webdevelopment #coding #programming #learninpublic #100DaysOfCode #frontenddevelopment #devcommunity #codingjourney #softwaredeveloper #techcommunity #dailylearning #codeeveryday

🚀 JavaScript Simplified Series — Day 28 Promises made async code better… But still… something feels messy 😵 👉 Too many .then() 👉 Hard to read 👉 Looks like chaining hell What if async code could look like normal synchronous code? 🤔 🔥 Solution → Async / Await 🔹 The Problem with Promises fetchData() .then(data => { console.log(data) return processData(data) }) .then(result => { console.log(result) }) .catch(err => console.log(err)) 👉 Works… but not clean ❌ 🔹 Async / Await (Cleaner Way) async function handleData() { try { let data = await fetchData() console.log(data) let result = await processData(data) console.log(result) } catch (err) { console.log(err) } } handleData() 👉 Looks simple & readable ✅ 🔍 What is happening? 👉 async → function always returns a promise 👉 await → waits for promise to resolve 🔹 Example function fetchData() { return new Promise(resolve => { setTimeout(() => { resolve("Data received") }, 2000) }) } async function getData() { let data = await fetchData() console.log(data) } getData() 👉 Output: Data received 🔥 Real Life Example Think of cooking 🍳 👉 Order ingredients 👉 Wait for delivery 👉 Then cook With async/await: Step by step… clean and clear 🔥 Simple Summary async → makes function async await → waits for result Result → clean & readable code 💡 Programming Rule Write async code like sync code.

🚀 JavaScript Simplified Series — Day 37 Till now… you’ve written all your JavaScript in one file 😵 👉 Everything mixed together 👉 Hard to manage 👉 Hard to scale What if you could **split your code into multiple files** and still use them together? 🤔 --- ## 🔥 Solution → Modules --- ## 🔹 What are Modules? Modules allow you to: 👉 Break code into **separate files** 👉 Reuse code easily 👉 Keep code clean & organized --- ## 🔹 Exporting Code ```javascript id="md1" // math.js export function add(a, b) { return a + b } ``` 👉 `export` makes function available outside --- ## 🔹 Importing Code ```javascript id="md2" // main.js import { add } from "./math.js" console.log(add(5, 3)) ``` 👉 Output: 8 --- ## 🔹 Default Export ```javascript id="md3" // user.js export default function greet() { console.log("Hello") } ``` Import: ```javascript id="md4" import greet from "./user.js" ``` --- ## 🔥 Real Life Example Think of a big project 🏢 👉 One file → login 👉 One file → dashboard 👉 One file → API All connected… but separate --- ## 🔥 Why Modules Matter? ✅ Clean code ✅ Reusable logic ✅ Easy to maintain ✅ Scalable projects --- ## 🔥 Simple Summary export → share code import → use code modules → organize code --- ### 💡 Programming Rule **Divide your code. Organize it. Scale it.** --- If you want to learn JavaScript in a **simple and practical way**, you can follow these YouTube channels: • Rohit Negi • Hitesh Choudhary (Chai aur Code) --- 📌 Series Progress Day 1 → What is JavaScript Day 2 → Variables & Data Types Day 3 → Type Conversion & Operators Day 4 → Truthy & Falsy + Comparison Operators Day 5 → If Else + Switch + Ternary Day 6 → Loops Day 7 → Break + Continue + Nested Loops Day 8 → Functions Basics Day 9 → Arrow + Default + Rest Parameters Day 10 → Callback & Higher Order Functions Day 11 → Arrays Basics Day 12 → Array Methods Day 13 → Array Iteration Day 14 → Advanced Array Methods Day 15 → Objects Basics Day 16 → Object Methods + this Day 17 → Object Destructuring Day 18 → Spread & Rest Day 19 → Advanced Objects Day 20 → DOM Introduction Day 21 → DOM Selectors Day 22 → DOM Manipulation Day 23 → Events Day 24 → Event Bubbling Day 25 → Event Delegation Day 26 → Async JavaScript Day 27 → Promises Day 28 → Async / Await Day 29 → Fetch API Day 30 → Event Loop Day 31 → Scope Day 32 → Hoisting Day 33 → Closures Day 34 → Prototypes Day 35 → Classes Day 36 → Inheritance Day 37 → Modules Day 38 → Debounce (Next Post) --- Follow for more 🚀 #JavaScriptSimplified #javascript #webdevelopment #coding #programming #learninpublic #100DaysOfCode #frontenddevelopment #devcommunity #codingjourney #softwaredeveloper #techcommunity #dailylearning #codeeveryday

🚀 JavaScript Simplified Series — Day 34 Objects are powerful… But what if you could **share properties and methods between objects automatically?** 🤔 Without copying code again and again 😵 This is where **Prototypes** come in 🔥 --- ## 🔥 The Problem ```javascript id="pt1" let user1 = { name: "Abhay", greet: function() { console.log("Hello") } } let user2 = { name: "Rahul", greet: function() { console.log("Hello") } } ``` 👉 Same function repeated ❌ 👉 Code duplication ❌ --- ## 🔥 Solution → Prototype JavaScript objects have a hidden property: 👉 **[[Prototype]]** Through this, objects can **inherit properties** --- ## 🔹 Example ```javascript id="pt2" function User(name) { this.name = name } User.prototype.greet = function() { console.log("Hello " + this.name) } let u1 = new User("Abhay") let u2 = new User("Rahul") u1.greet() u2.greet() ``` 👉 Output: Hello Abhay Hello Rahul --- ## 🔍 What’s happening? 👉 `greet()` is not inside object 👉 It is shared via prototype 📌 Memory efficient + reusable --- ## 🔥 Real Life Example Think of a **template 🧾** 👉 Same format 👉 Different data Like: Form template → reused for all users --- ## 🔥 Prototype Chain If property not found: 👉 Object → Prototype → Next Prototype → null --- ## 🔥 Simple Summary Prototype → shared properties Avoid duplication Enable inheritance --- ### 💡 Programming Rule **Don’t repeat logic. Share it using prototypes.** --- If you want to learn JavaScript in a **simple and practical way**, you can follow these YouTube channels: • Rohit Negi • Hitesh Choudhary Choudhary (Chai aur Code) --- 📌 Series Progress Day 1 → What is JavaScript Day 2 → Variables & Data Types Day 3 → Type Conversion & Operators Day 4 → Truthy & Falsy + Comparison Operators Day 5 → If Else + Switch + Ternary Day 6 → Loops Day 7 → Break + Continue + Nested Loops Day 8 → Functions Basics Day 9 → Arrow + Default + Rest Parameters Day 10 → Callback & Higher Order Functions Day 11 → Arrays Basics Day 12 → Array Methods Day 13 → Array Iteration Day 14 → Advanced Array Methods Day 15 → Objects Basics Day 16 → Object Methods + this Day 17 → Object Destructuring Day 18 → Spread & Rest Day 19 → Advanced Objects Day 20 → DOM Introduction Day 21 → DOM Selectors Day 22 → DOM Manipulation Day 23 → Events Day 24 → Event Bubbling Day 25 → Event Delegation Day 26 → Async JavaScript Day 27 → Promises Day 28 → Async / Await Day 29 → Fetch API Day 30 → Event Loop Day 31 → Scope Day 32 → Hoisting Day 33 → Closures Day 34 → Prototypes Day 35 → Classes (Next Post) --- Follow for more 🚀 #JavaScriptSimplified #javascript #webdevelopment #coding #programming #learninpublic #100DaysOfCode #frontenddevelopment #devcommunity #codingjourney #softwaredeveloper #techcommunity #dailylearning #codeeveryday

🚀 JavaScript Simplified Series — Day 25 Imagine this 👇 You have a list of 100 items… And you want to add a click event on each item 😵 Will you do this? let items = document.querySelectorAll("li") items.forEach(item => { item.addEventListener("click", function() { console.log("Item clicked") }) }) Works… but not efficient ❌ 👉 What if new items are added later? 👉 You’ll have to add event again 😩 🔥 Solution → Event Delegation 🔹 Idea Instead of adding event to every child… 👉 Add event to parent And detect which child was clicked 🔹 Example <ul id="list"> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul> let list = document.querySelector("#list") list.addEventListener("click", function(e) { console.log(e.target.innerText) }) 👉 Click any item → it works 😎 🔍 How it works? Because of event bubbling 👉 Event child se parent tak travel karta hai Parent catches it 🔹 Why Event Delegation is Powerful? ✅ Less code ✅ Better performance ✅ Works for dynamic elements 🔥 Real Life Example Think of a classroom 🎓 Instead of asking each student individually… 👉 Teacher asks whole class Jo respond kare → identify karo 🔥 Simple Summary Event Delegation → parent handles child events Uses → event bubbling Benefit → efficient & scalable 💡 Programming Rule Don’t attach events everywhere. Use delegation smartly.

🚀 JavaScript Simplified Series — Day 24 You clicked a button… But something strange happened 😳 👉 Button ka event bhi chala 👉 Parent div ka event bhi chala 👉 Aur kabhi kabhi pura page react kar leta hai Why? 🤔 --- ## 🔥 This is called → Event Bubbling --- ## 🔹 Real Example ```html id="eb1" <div id="parent"> <button id="child">Click Me</button> </div> ``` ```javascript id="eb2" let parent = document.querySelector("#parent") let child = document.querySelector("#child") child.addEventListener("click", function() { console.log("Button Clicked") }) parent.addEventListener("click", function() { console.log("Div Clicked") }) ``` 👉 Output when button is clicked: Button Clicked Div Clicked --- ## 🔍 What’s happening? Event flow: 👉 First child (button) 👉 Then parent (div) 📌 Event travels **inside → outside** This is called **Event Bubbling** --- ## 🔹 Why does this happen? Because browser follows a flow: 👉 Target element → Parent → Body → Document --- ## 🔹 How to Stop Bubbling? Sometimes you don’t want parent event to trigger 😎 ```javascript id="eb3" child.addEventListener("click", function(e) { e.stopPropagation() console.log("Button Clicked") }) ``` 👉 Now only button event runs --- ## 🔥 Real Life Example Think of a **water bubble 🫧** Bubble upar jaati hai… 👉 Same way event travels upward --- ## 🔥 Simple Summary Event Bubbling → event moves upward Parent bhi trigger hota hai stopPropagation() → bubbling stop karta hai --- ### 💡 Programming Rule **Understand event flow warna bugs samajh nahi aayenge 😄** --- If you want to learn JavaScript in a **simple and practical way**, you can follow these YouTube channels: • Rohit Negi • Hitesh Choudhary (Chai aur Code) --- 📌 Series Progress Day 1 → What is JavaScript Day 2 → Variables & Data Types Day 3 → Type Conversion & Operators Day 4 → Truthy & Falsy + Comparison Operators Day 5 → If Else + Switch + Ternary Day 6 → Loops Day 7 → Break + Continue + Nested Loops Day 8 → Functions Basics Day 9 → Arrow + Default + Rest Parameters Day 10 → Callback & Higher Order Functions Day 11 → Arrays Basics Day 12 → Array Methods Day 13 → Array Iteration Day 14 → Advanced Array Methods Day 15 → Objects Basics Day 16 → Object Methods + this Day 17 → Object Destructuring Day 18 → Spread & Rest Day 19 → Advanced Objects Day 20 → DOM Introduction Day 21 → DOM Selectors Day 22 → DOM Manipulation Day 23 → Events Day 24 → Event Bubbling Day 25 → Event Delegation (Next Post) --- Follow for more 🚀 #JavaScriptSimplified #javascript #webdevelopment #coding #programming #learninpublic #100DaysOfCode #frontenddevelopment #devcommunity #codingjourney #softwaredeveloper #techcommunity #dailylearning #codeeveryday
