JavaScript Array Methods: A Complete Guide to Map, Filter, and Reduce

* Mastering JavaScript Array Methods: map(), filter(), and reduce() * 1] * Introduction to Arrays in JavaScript * In the world of programming and Data Structures & Algorithms (DSA), Arrays are fundamental. An array is a crucial data structure used to store a collection of multiple data items in a single variable. Whether it's a list of integers, decimals, or characters, arrays help us manage data efficiently. What is an Array? An array is an ordered collection of data. It can be sorted or unsorted. ● Integers: const numbers = [1, 2, 3, 4]; ● Decimals: const prices = [0.1, 0.5, 0.2]; ● Strings/Characters: const chars = ['h', 'e', 'l', 'l', 'o']; (Note: Strings can be converted into arrays using the split() method for easier manipulation.) To operate on the data stored within these arrays, JavaScript provides several powerful built-in methods. Let’s dive into the most important ones. map() Method , filter() Method , reduce() Method so Let’s see one by one. 2] The map() Method The map() m
