Removing a value from the dictionary

Next, we will implement the remove method. It is very similar to the remove method from the Set class; the only difference is that we will first search for the key (instead of value), as follows:

remove(key) {  if (this.hasKey(key)) {    delete this.table[this.toStrFn(key)];    return true;  }  return false;}

Then, we will use the JavaScript delete operator to remove the key (transformed into a string) from the table object. In case we are able to remove the value from the dictionary, we will also return true, otherwise, we will return false.
