WebHuffman Coding is a method of lossless compression. Lossless compression is valuable because it can reduce the amount of information (or in your computer, memory) needed to communicate the exact same message. That means that the process is perfectly invertible. Lossy compression on the otherhand will lose information.

One of the important features of the table produced by Huffman coding is the prefix property: no character’s encoding is a prefix of any other (i.e. if 'h' is encoded with 01 then no other character’s en-coding will start with 01 and no character is encoded to just 0).
