Conquer the JavaScript Interview: Hash Map Data Structure [Beginner Skill Level]

Link to this Playlist:

Part 1:

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 hash map data structure in JavaScript. Which, you'll learn, is what an Object already is! The JavaScript Object is an abstraction and simplified data type you program with everyday that is a hash map under the hood. We discuss the pros and cons, uses, issues, and general concepts in this video. Then we go on to implement a simple version of it and correspond it to a helpful analogy of a library.
