JavaScript Arrays: A Complete Beginner’s Guide
JavaScript arrays are powerful data structures used to store multiple values in a single variable. They allow developers to organize, manage, and manipulate data efficiently using indexes. Arrays in JavaScript can hold different data types, such as numbers, strings, objects, or even other arrays. Common array methods like push(), pop(), shift(), unshift(), map(), filter(), and reduce() make it easier to perform operations on stored values. Arrays are widely used in loops, data handling, and real-world applications like managing lists, records, or collections. Understanding JavaScript arrays is essential for mastering coding, problem-solving, and building dynamic web applications.
