JavaScript Array Iteration Methods – forEach, map, filter, reduce, every & some (Part 5)

Welcome to Day 11 of our JavaScript Learning Series 🚀 In this video, we cover Part 5 of JavaScript Arrays, focusing on array iteration methods that are used extensively in modern JavaScript, React, Angular, and backend development. These methods allow you to loop, transform, filter, validate, and reduce data in a clean and readable way. Mastering these methods is essential for real-world projects and interviews. 🔥 What you’ll learn in this video: What are array iteration methods Why iteration methods are preferred over traditional loops Understanding and using: forEach – loop through array elements map – transform array values filter – select specific elements reduce – reduce array to a single value every – check if all elements satisfy a condition some – check if at least one element satisfies a condition Differences between map, filter, and reduce When to use forEach vs map Real-world use cases of array iteration Common mistakes beginners make with iteration methods 🛠 Tools & Technologies Used: JavaScript (ES6 and modern JavaScript) Node.js Visual Studio Code (VS Code) 📚 Official & Trusted Learning Resources: All references below are from globally trusted and authoritative sources: JavaScript Array Iteration Methods (MDN – Mozilla): https://developer.mozilla.org/en-US/d...
