JavaScript Sets and Maps

This video tutorial introduces two important data structures in JavaScript: sets and maps. Sets are collections of unique items, and the video demonstrates how to create, add, delete, and iterate through sets. It also explains how sets automatically reject duplicate values. The tutorial then shifts focus to maps, which store data in key-value pairs. The video shows how to create maps, add entries, and iterate through them using loops. By the end, viewers will understand the basic operations and use cases for sets and maps in JavaScript.
