✅ Day 24/25 — JS Code Execution Aaj samjha how code runs: 🔹pehle Global Execution Context banta hai (this + memory) 🔹Memory phase: vars undefined, functions store 🔹Execution phase: line by line run hoga, function call =new context @Hiteshdotcom @ChaiCodeHQ #MasterJiChallenge
✅Day 23/25 — IIFE (Immediately Invoked Functions) Ek function jo define karte hi turant run ho jata hai — isse global scope clean rehta hai, variables bahar leak nahi hote, aur private scope create ho jata hai. @Hiteshdotcom @ChaiCodeHQ #MasterJiChallenge #JavaScript
✅ Day 22/25 — this & Arrow Functions Revised: 🔹Objects me this → current object 🔹Functions me this undefined 🔹Arrow funcs inherit parent this 🔹Explicit vs implicit return samjha 🔹Object return → use () not {} @Hiteshdotcom @ChaiCodeHQ #MasterJiChallenge #JavaScript
✅ Day 21/25 — Scope level mini Hoisting in JS Aaj samjha kaise inner functions parent variables use or access karte hain (same in if–else & loops). Aur function declairation hoist hote hain, function expression nahi ⚡ @Hiteshdotcom @ChaiCodeHQ #MasterJiChallenge #JavaScript
✅ Day 20/25 — Global & Local Scope Aaj seekha: • Scope means {} → area jaha variable accessible hota hai • let & const → block scoped • var → function/global scoped (leak ho sakta hai) • Scope is different in Node.js & Browser @Hiteshdotcom @ChaiCodeHQ #MasterJiChallenge
