WebThere are two main types of entropy coders, Huffman and arithmetic. Huffman’s big advantage is speed, while arithmetic coding gives better compression. Deflate chose to use Huffman, and even today, it’s a good tradeoff in speed vs compression. But before we implement Huffman, we need to be able to read and write bits, not bytes.

Huffman in 1952, Huffman coding has been regarded as one of the most efficient and optimal methods of compression.
