aFunction

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. REV EDIT: Gist repos can be downloaded with git tools by following the formula:

git clone https://github.com/gist/#repo-number# (the username has been replaced with 'gist') END EDIT

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.

For more information

See the 140byt.es site for a showcase of entries (built itself using 140-byte entries!), and follow @140bytes on Twitter.

To learn about byte-saving hacks for your own code, or to contribute what you've learned, head to the wiki.

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

REV EDIT: If your statement comes in at under 128 chars and it's visually interesting then it can be entered into the 128b/JavaScript category on Pouet.net... END EDIT

/* aFunction: gives what it takes.
* First off, I'm evaluating an expression, rather than simply
* defining a function, since the rules specified expression, so
* I want to point out that a function definition is but one of
* many possible useful expressions (I am also making use of a
* functions as you can clearly see)...just want to open this up a bit
*
* BTW, a NAMED function called in this way is NOT in the global scope,
* so if you use this expression on a page and then open the js console
* and enter 'aFunction' you will see the Refrence Error:
* "aFunction is not defined"
* So, why use a name in a function definition expression? According to
* "JavaScript Pocket Reference" by David Flanagan:
*
* "If a function definition expression includes a name, the local
* function scope for that function will include a binding of that
* name to the function object. In effect, the function name becomes
* a local variable within the function." (Flanagan, 114)
*
* quirky? kinky? javascript :)
