## arrays and strings ## arrays and strings and hash objects

### hash objects
<br>
* hash tables are data structure that organizes data using hash functions, in order to support quick insertion and search (map keys to buckets).
* ideally, a perfect hash function will be a 1-1 mapping between the key and the buckets. however, in most cases, a hash function is not perfect and there is a tradeoff between the amount of buckets and the capacity of a bucket.
* if the hash function is not a 1-1 mapping, collisions must be handled:
- how to organize the values in the same bucket?
- what if too many values are assigned to the same bucket?
- hwo to search for a target value in a specific bucket?
