WebJan 26, 2024 · Hashing means using some function or algorithm to map object data to some representative integer value. This so-called hash code (or simply hash) can then be used as a way to narrow down our search when looking for the item in the map. Generally, these hash codes are used to generate an index, at which the value is stored.
