JavaScript Full Revision 🔥 | Arrays, Closures, Prototype, LocalStorage | Practical Examples

JavaScript Full Revision 🔥 | Arrays, Closures, Prototype, LocalStorage | Practical Examples Is video mein hum JavaScript ka complete practical revision karenge step-by-step with real coding examples. Ye video specially un developers ke liye hai jo: ✔️ JavaScript revise karna chahte hain ✔️ Interview preparation kar rahe hain ✔️ Concepts ko sirf theory nahi balkay practical implementation ke sath samajhna chahte hain ✔️ Beginner se intermediate level tak strong foundation banana chahte hain 🔹 1) Arrays in JavaScript (Basics + Methods) Is part mein hum arrays ko basic se advanced level tak samjhenge: Basic Array Methods: push() → array ke end mein value add karna pop() → array ke end se value remove karna shift() → array ke start se value remove karna unshift() → array ke start mein value add karna slice() → array ka portion copy karna (without changing original array) splice() → array ko modify karna (add, remove, replace elements) ➡️ Practical examples ke sath real-time use cases 🔹 2) Array Higher Order Methods (Functional Programming) Is section mein modern JavaScript ke powerful methods: map() → data transform karna forEach() → iteration ke liye find() → condition ke basis par first match findIndex() → index return karta hai findLastIndex() → last matching element ka index filter() → multiple values filter karna reduce() → data aggregation, total, sum, cart logic, etc ➡️ Real-world examples (cart system, search system, filtering, totals) 🔹 3) Prototype Based Inheritance in JavaScript JavaScript ka core internal system explain kiya gaya hai: _proto_ kya hota hai prototype kya hota hai Object → Function → Prototype chain Prototype chaining Inheritance ka real mechanism Constructor functions ke sath inheritance ➡️ Visual + practical examples ke sath deep understanding 🔹 4) Closures & Currying (In Detail) Closures: Closure kya hota hai Currying: Currying function kya hota hai Function returning function concept Multiple arguments ko step-by-step functions mein convert karna Real-world examples (discount system, configuration functions) ➡️ Real coding + interview-based examples 🔹 5) Local Storage in JavaScript (Complete Practical Use) Is section mein browser storage system complete detail ke sath: localStorage.setItem() localStorage.getItem() JSON.stringify() → data store karne ke liye JSON.parse() → data retrieve karne ke liye Objects & arrays ko localStorage mein save karna LocalStorage se data retrieve karna Page reload ke baad data persist rehna ➡️ Practical example: user data, cart data, settings storage 🎯 Why This Video is Important? Ye video aapko: ✅ Strong JavaScript foundation degi ✅ Interview concepts clear karegi ✅ Real-world project logic samjhayegi ✅ Advanced JS understanding build karegi ✅ Clean coding mindset develop karegi 👉 Agar aap JavaScript seriously master karna chahte ho, to ye video aapke liye must-watch hai.
