Summary
In this chapter, we delved into the inner workings of set data structures by implementing a custom MySet class. This hands-on approach mirrors the core functionality of the Set class introduced in ECMAScript 2015, giving you a deeper understanding of how sets operate under the hood. We also extended our exploration beyond the standard JavaScript Set by implementing additional methods like union, intersection, difference, and subset, enriching your toolkit for working with sets.
To put our newfound knowledge into practice, we tackled a real-world LeetCode problem, demonstrating the power of sets in solving algorithmic challenges.
In the next chapter, we will shift our focus to non-sequential data structures, specifically hashes and dictionaries. Get ready to discover how these versatile structures enable efficient data storage and retrieval based on key-value pairs!
