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.
