Conquer the JavaScript Interview: Array Intersect [Beginner Skill Level]

Link to this Playlist:

This is a part of my Algorithms and Data Structures playlist series. We cover a lot of common interview questions asked during whiteboards for entry level developers. Learning to master these takes time, practice, and pattern recognition. So I'll be helping you equip a toolbelt and filling it with as many tools as I can to help prepare you crush those interviews! Remember: "Luck is where practice meets opportunity."

In this video, we cover the topic of finding the intersection of two arrays in JavaScript. We explore two different methods for solving this problem: using a Set and using an Object hashmap. We discuss the pros and cons of each approach, as well as their time and space complexities. Additionally, we dive into real-world applications of this simple algorithm and how it relates to broader programming concepts.
