140byt.es

A tweet-sized, fork-to-play, community-curated collection of JavaScript.

How to play

  1. Click the Fork button above to fork this gist.
  2. Modify all the files to according to the rules below.
  3. Save your entry and tweet it up!

Keep in mind that thanks to the awesome sensibilities of the GitHub team, gists are just repos. So feel free to clone yours and work locally for a more comfortable environment, and to allow commit messages.

Rules

All entries must exist in an index.js file, whose contents are

  1. an assignable, valid Javascript expression that
  2. contains no more than 140 bytes, and
  3. does not leak to the global scope.

All entries must also be licensed under the WTFPL or equally permissive license.

The 140byt.es site hasn't launched yet, but for now follow @140bytes on Twitter.

140byt.es is brought to you by Jed Schmidt. It was inspired by work from Thomas Fuchs and Dustin Diaz.

I think this is one of the most wonderful 140bytes gists I've ever seen.
@p01 amazing work!

Save 3 bytes by the way.

function(f,t,S){for(t=0;++t<3e5;)S+=String.fromCharCode(eval(f));return'RIFF_oO_WAVEfmt '+atob('EAAAAAEAAQBAHwAAQB8AAAEACAA')+'data'+S}

Thanks

One thing I considered was getting rid of the 3e5 and pass an argument T instead. Same size but more flexible, at the cost of having to pass the "duration/number of blocks" all the time.

@tsaniel: That's basically offloading the empty string to the function call. Mmmmh, not sure that gives us much for the 'slow' version of Music SoftSynth, but it does bring the 'fast' version down to 139 bytes:

function(f,S,t){return'RIFF_oO_WAVEfmt "+atob('EAAAAAEAAQBAHwAAQB8AAAEACAA')+"data'+eval("for(t=0;++t<3e5;)S+=String.fromCharCode("+f+")")}

There couldn't have been a 140byt.es without some p01 magic... This is sick. Just sick....

\:D/ I managed to gain one byte while still only passing the formula

Another nice usage of |=, gook job @p01!

Somehow a typo made its way into test.html, fix here: https://gist.github.com/2875542
