I was studying russkey.mozdev.org source code to learn how to write Firefox extension.
Found this style of function call in javascript.
var collection = { hello : function() { document.write("Hello World!"); }, understand : function() { document.write("<br/>Understand!"); }, bye : function() { document.write("<br/>bye!"); } }; var m = new collection.hello(); var n = new collection.understand(); var o = new collection.bye();
The output will
Hello World! Understand! bye!
