Creating a HashTable class

We will also use an associative array (object) to represent our data structure as we did in the Dictionary class.

As usual, let's start with the structure of our class using the following code:

class HashTable {  constructor(toStrFn = defaultToString) {    this.toStrFn = toStrFn;    this.table = {};  }}     

Next, we need to add some methods into our class. We will implement three basic methods for every class:

  • put(key, value): This method adds a new item to the hash table (or it can also update it)
  • remove(key): This method removes the value from the hash table using the key
  • get(key): This method returns a specific value searched by the key
