Implementing Hashmaps

To implement a hash table using JavaScript, we will do three things: create a hash table class, add a hash function, and implement a method for adding key/value pairs to our table.

To implement a hash map, the HashMap constructor method will create an empty array that will hold values. A hashing function will return an index in the array where the value will be stored. While going through the following exercises, remember that the purpose of this lesson is to gain a deeper understanding of the data structure rather than creating a production-quality data structure.

This week we Implemented Hashmap, next week we will tackle our very first Leetcode problem.
