Guide to Ecmabot

Ecmabot is a bot used in ##javascript on irc.freenode.net which was created to execute tiny JavaScript snippets and to store factoids for later retrieval.

JavaScript execution

To use the interpreter:

>> console.log("Hello, world.");
<ecmabot> eboy: undefined; Console: 'Hello, world.'
