I love these tiny decoders, even if their use cases are limited. To me this is as much art as it is programming.<p>For Javascript I ran into these two recently:<p>Tiny LZW(ish) encoder/decoder. The decoder is 141 bytes: <a href="https://gist.github.com/mr5z/d3b653ae9b82bb8c4c2501a06f3931c6" rel="nofollow">https://gist.github.com/mr5z/d3b653ae9b82bb8c4c2501a06f3931c...</a><p>RegPack, a non-standard encoding, but an awesome approach for small chunks (1-4KByte is optimal) of self contained compressed code, using regular expressions for decoding: <a href="https://github.com/Siorki/RegPack" rel="nofollow">https://github.com/Siorki/RegPack</a>
