📦 bloomfilter

Bloomfilter implements a space-efficient probabilistic data structure used to test whether an element is a member of a set. False positives are possible, but false negatives aren't. This library provides a fast and lightweight implementation for Node.js and browsers. It allows you to define the size and error rate, serialise the Bloom filter to JSON for persistent storage, and perform basic operations like adding elements and checking membership. Ideal for scenarios needing quick approximations for set membership with memory constraints.
