Data structures are crucial for organizing and managing data in JavaScript. They provide structured ways to store and access information, improving code efficiency and readability. Arrays, objects, and maps are common data structures in JavaScript. Arrays are ordered collections of elements, accessed by their index. Objects store data in key-value pairs, offering a more flexible way to organize information. Maps are similar to objects but provide more advanced methods for managing key-value pairs. Choosing the right data structure for a specific task is vital. Understanding the strengths and weaknesses of each structure allows you to write optimized code. For example, using an array for a list of items or an object for representing a user’s profile.
