The put method

Let's implement the first method, the put method, as follows:

put(key, value) {  if (key != null && value != null) {    const position = this.hashCode(key);    if (this.table[position] == null) { // {1}      this.table[position] = new LinkedList(); // {2}    }    this.table[position].push(new ValuePair(key, value)); // {3}    return true;  }  return false;}

In this method, we will verify whether the position we are trying to add the value to already has other values in it ({1}). If this is the first time we are adding an element in this position, we will initialize it with an instance of the LinkedList class ({2} - which we learned in Chapter 6, Linked Lists). Then, we will add the ValuePair instance to the LinkedList instance using the push method ...
