I had a lot of fun to see that the other day :-) > "Binaryen" is pronounced in the same manner as "Targaryen": bi-NAIR-ee-in. Or something like that? Anyhow, however Targaryen is correctly pronounced, they should rhyme. Aside from pronunciation, the Targaryen house words, "Fire and Blood", have also inspired Binaryen's: "Code and Bugs." https://github.com/WebAssembly/binaryen https://github.com/WebAssembly/binaryen Do you know XZ Embedded? http://tukaani.org/xz/embedded.html http://tukaani.org/xz/embedded.html I wonder if it could improve startup (with emterpreter?).

I hadn't heard of XZ embedded. Might be worth measuring it, but it would be competing with native gzip in the browser, which is hard to beat on speed. But maybe better compression would be worth it?

  LZHAM is interesting in that area. Speed that competes with gzip and compression that competes with LZMA. https://github.com/richgel999/lzham_codec https://github.com/richgel999/lzham_codec

    Interesting. It reminds me encode.ru :) Do you know the size of the compiled code?

        Very cool!

  The most interesting feature (for me) is its small size: "Compiled code is 8–20 KiB." zlib is heavier (about 200Ko). It could be used to make self-extractible asm.js programs or to compress some embedded resources (like files from "--embedd", fonts, images...).
