loseloseHashCode(key) {  if (typeof key === 'number') { // {1}    return key;  }  const tableKey = this.toStrFn(key); // {2}  let hash = 0; // {3}  for (let i = 0; i < tableKey.length; i++) {    hash += tableKey.charCodeAt(i); // {4}  }  return hash % 37; // {5}}hashCode(key) {  return this.loseloseHashCode(key);}

The hashCode method simply evokes the loseloseHashCode method, passing the key as the parameter.

In the loseloseHashCode method, we will first verify whether the key is a number ({1}). If it is a number, we simply return it. Next, we will generate a number based on the sum of each char ASCII ...
