Please refer to our contribution guidelines; a proper PR should be using ES modules (not HTML), have a JSDoc comment, tests, and not be invoking side effects like console.log. This implementation is also not really reusable, since it uses a fixed-size hash table hardcoded to 10 slots, and does not seem to deal with collisions at all (I would consider that a broken hash table).
