Day 25 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom Learned control flow with if-else & switch - Explored truthy & falsy values - Checked empty arrays & objects - Understood Nullish Coalescing(??) - Used Ternary Operator for quick conditions #MasterjiChallenge #JavaScript

Day 24 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom • Learned about Execution Context & Call Stack • JS starts with Global Execution Context • Each function creates its own context • Two phases: Memory & Execution • Managed by Call Stack (LIFO)

Day 23 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom Learned IIFE (Immediately Invoked Function Expression) • Executes immediately after creation • Avoids global scope pollution • Can be named or anonymous • Pass params → ((name)=>{})(‘Nausheen’) • Always end with ;

Day 22 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom - this & Arrow Functions in JS -this depends on how a function is called - Arrow functions inherit this (lexical scope) - Node.js → this = {} | Browser → this = window - Explicit return → {} | Implicit return → no {}

Day 21 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom Scope & Hoisting in JS 🔹 Inner → can access outer vars 🔹 Outer → can’t access inner vars 🔹 Function declarations → hoisted 🔹 Function expressions / arrow → not hoisted Know your scopes to avoid tricky bugs!

Day 18 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom Learnt how functions work declaring, calling, passing parameters, using default values like function loginUserMessage(username="sam"), returning values, and checking missing arguments with if(!username). #ChaiAurCode

Day 17 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom Learned object destructuring + JSON basics and used a JSON formatter to read API data clearly. Clean code feels good #ChaiAurCode #MasterjiChallenge #JavaScript

Day 16 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom Learned object merging using Object.assign(target, source), nested object access, Object.keys/values/entries & hasOwnProperty. Object handling feels much clearer now 💻🔥 #MasterJiChallenge

Day 15 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom learned Objects in depth in JavaScript 💻 object literals, dot vs bracket access, symbols, Object.freeze(), and functions with string interpolation 🔥 #ChaiAurCode #MasterJiChallenge

Day 14 of #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom Array Part 2 💻 Learned concat, spread, flat(), and array utils like isArray(), from(), of() merging & flattening made easy! 🔥 #ChaiAurCode #MasterJiChallenge

Day 13 ☕ #JavaScriptChallenge by @ChaiCodeHQ @Hiteshdotcom learned Arrays in JS! 📚 Explored push, pop, shift, unshift, slice vs splice, and deep vs shallow copy 🔥 #ChaiAurCode #MasterjiChallenge

Day 12 of #JavaScriptChallenge by @ChaiCodeHQ & @Hiteshdotcom Explored Date & Time in JS ⏰ Learned new Date(), custom dates, timestamps with Date.now(), getMonth, getDay & toLocaleString() formatting 🔥 #ChaiAurCode

Day 11 of #JavaScriptChallenge by @ChaiCodeHQ & @Hiteshdotcom learned about Numbers & Math in JS! 💻 From .toFixed(), .toPrecision(), .toLocaleString() to Math.abs(), .round(), .floor(), and the powerful Math.random() with range formula 🎯 #ChaiAurCode #MasterjiChallenge

Day 10 of #JavaScriptChallenge by @ChaiCodeHQ ☕ 💻 & @Hiteshdotcom Explored Strings in JS! From backticks & interpolation to methods like trim, slice, replace & split. #ChaiAurCode #MasterjiChallenge

Day 9 of #JavaScriptChallenge by @ChaiCodeHQ & @Hiteshdotcom learned Stack vs Heap memory in JavaScript! All primitive data types are stored in the stack (copied by value), while non-primitive (reference) types are stored in the heap (copied by reference). #MasterjiChallenge
